# Analysis Of N Rattus And N Squamipe

806 Words 4 Pages
The two-sample t procedure is appropriate to use in this experiment in order to see if there is a difference in the two

population means of stride length in the two different species, N. rattus and N. squamipes. This is because the boxplots

appear to be roughly symmetrical, as well as, both normal quantile-quantile plots look roughly linear. Considering

two-sample t-procedures are quite robust to violations of the normality assumption, the t-procedure will likely

perform well in this scenario. It is important to note that the second assumption of an independent simple random

sample may not be reasonable as each species of rat came from a single municipality. This may not be representative

of the entire population of the species. In spite of this, using a
The point estimate of the true mean

difference between the lowest detectable amplitudes (post space flight sensitivity –

pre-space flight sensitivity) is 33.866 micrometers. This provides evidence that

astronauts’ foot sole skin becomes hyposensitive following space shuttle missions.

We can be 95% confident that the true mean difference in the lowest detectable

amplitude of a 25 Hz frequency on the big toe of an astronaut before and after a

space shuttle mission (after-before), under the conditions of this study, lies between

5.094012 and 62.637988 micrometers. On average, the sensitivity of astronauts’

foot sole skin post space flight is less than before the space flight. It is important to

note that since this entire interval is to the left of 0, we can reject the null

• ## The Ranger Program Essay

The first probe, Luna 1, was sent to the moon on January 2, but missed its target. In September of the same year, Luna II successfully landed on the moon, while taking several pictures and collecting a lot of valuable data. In spite of all their setbacks, the United States established the Ranger programs in 1959. The Ranger program’s objective was to send spacecrafts to the moon. It took seven attempts for NASA to achieve their goal.…

• ## Domestic Space Exploration Essay

Learning requires failure. When planes were first invented, there were many trials and failures, but as they have progressed, the failures have become few and far between. Same goes for the space shuttle program. There were crashes or failures that were quite costly, but that was to be expected seeing as how it was only the beginning of the research and development of space shuttles. It seems unfair to judge the space program based on its early days.…

• ## Effects Of Pre-Natal Stress On Rat

This is important because rats have a smaller amount of neurons than human beings. Thus, the effect of PNS might be stronger in rats because of that. A third possible study that could be conducted is to expose pregnant rats to stressors throughout the entire term of pregnancy instead of only the third trimester. This would allow researchers to observe if prolonged stress could increase the impact of PNS on the outcome of the offspring. This is important because this could help researchers understand how factors such as pollution in the environment could affect pregnant…

• ## The Moon's Conspiracy Theory: Did We Land On The Moon?

However, when the astronauts passed through the first, and more deadly radiation belt, it took them only a couple of minutes, and the lesser belt around one and a half hours. The amount of radiation they received, including the journey home, is not enough to be lethal. In fact the amount they received is about the same that workers are allowed to receive working at nuclear energy fields (Fox). In 1968 the Soviets did a moon test off their own with living matter, with their Zond program. The Zond Five was launched and did an orbit around the moon, then returned.…

• ## Apollo 11 Pros And Cons

Theorists believe that the astronauts could not have left such well-defined footprints because there is no moisture in a vacuum. When moisture is present the soil will compact better than without moisture therefore leaving a much more distinctive print. The NASA transcripts show Neil Armstrong said on July 21, 1969, at 2:56 am as he stepped off the moon, “the surface is fine and powdery” and “I only go in a small fraction of an inch, maybe an eighth of an inch, but I can see the footprints of my boots and the treads in the fine, sandy particles” (Armstrong). Each particle of the lunar regolith is very sharp. These particles with their sharp, jagged edges allow for them to be compressed and compacted much better than soil on earth.…

• ## Effects Of Space Travel On Human Health

Additionally, the astronauts that will be working and living in space will be compared to a control group that is living and working in a space mission simulator on Earth. Only a small sample of men have spent over a year in space, but the proposed study is much longer and proposes to include females into the study. To conceptualize the variables in the study, multiple subjective and objective measurements for stress, anxiety, sleep, and physiological changes have been proposed. Next, the proposed study would not be able to measure all variables that would be important for better preparing for long-term space missions. The participants in the study would be working and living in space, which limits the data that can be gathered or measures that can be collected.…

• ## Edaravone Case Study

By intracisternal injection into rats with mild meningitis, neurological function as well as the neuroprotective actions had been significantly improved by the use of edaravone. With an intraperitoneal injection of edaravone, retina from ischemic-reperfusion injury in rats can be protected through reducing oxidative stress and apoptosis of retinal neurons. Also, edaravone can be injected into the rats intraocularly after the experimental rats was induced with optic nerve injury as edaravone actively ameliorated ONI-induced ROS production and inner retinal degeneration. Intraaortic route of edaravone administration is also useful in inhibiting swelling of mitochondria in hearts with edema symptom. Edaravone can also be administered via topical application.…

• ## Explorer 1 Essay

It brought a cosmic ray detector and a tape recorder into orbit with it, and unlike Explorer 2, this satellite was able to get results. Explorer 3 deceased after 93 days in orbit. Next up in the Explorer Program was Explorer 4, it was created to study the Van Allen radiation belts and the effects of nuclear detonations on it. It became the first satellite to evaluate electric particles in the radiation belt. This was the last Explorer satellite (in the series) to make it into orbit.…

• ## The Early Stages Of The Space Race

“That’s one small step for man… but one giant leap for mankind.” America had learned through our loses to the Soviets in the space race. Soviet Union progress scared America. Project Apollo employed over 400,000 people. Landing on the moon concluded the space race and convinced world we won. The accomplishments of landing on the moon, building bomb shelters, and passing education acts all contributed…
