Normal distribution

The details of the scores for each of the six factors analyzed in the NASA-TLX questionnaire (Fig. 3) reveal that the use of the robot impacts mostly on the mental demand of the task and on the effort required from the caregiver, while actually the use of the robot increases the temporal demands of the tasks. B. Division of the Caregivers Time Regarding the time spent with personalized attention to users, a total of 862 segments were annotated by the two annotators. Their annotation were in…

One result of random genetic drift and gene substitution is mutant alleles, however the probability that these mutations become fixed in a population is not solely dependent on the advantageous nature of the allele, rather the probability of fixation is determined by the allele frequency, the selective advantage or disadvantage, and the effective population size. The probability of fixation for a particular allele is demonstrated by the equation where probability is equal to 1 minus the…

CS2301 df5 Questions: Using Figure 17.5 from the textbook explain why we have a “big mess” of our free space memory allocation Answer: Below figure show one example of putting the memory. Quoted: ARPACI-DUSSEAU. R., ARPACI-DUSSEAU, A. (2012, ch17-8) In above example, assume total size is 4096, header eat 16k, each chunk total eat 108k (100 + 4 k header + 4 k chunk). In theory (assume perfect allocation), no waste space resulted. Then total 37 chunk block (108k) can be fitted. However, the…

Clover covered her ears after eavesdropping on a bunch of people criticizing her fashion choices. She understands that her fashion choice isn't the trendiest around but she felt comfortable wearing the warm sweater, and sweatpants. Compared to the popular students that wore clothes that barely covered their skin, Clover was considered an outcast who has the poorest taste in everything she did. "I swear I'm going to change." Clover whispered. "I'm going to be the popular girl in High School."…

1. Z- test is used when the sample size is large enough n>30, the population standard deviation is known, and population is normally distributed. Example: Is the mean of systolic blood pressure level for women use of oral contraceptives is identical with women does not use of oral contraceptives, the sample mean > 30, we known the population standard deviation and it is normally distributed. H0: µ1=µ2 H1: µ1≠µ2 2. t- test is used when the population standard deviation is…

What are the possible fixes to the problem? What are the consequences of the fixes? Problem 1: The residuals should be normally distributed. This can be detected visually using the standardized normal probability plot and histogram. If all the residuals are not within two standard deviations in the normal probability plot or form a bell curve in the histogram, then they are not normally distributed. When the residuals are not normally distributed, it means the…

and 53 males. b. There are 21 people under the age range of 13-35, which account for 21.6% of the total 97 in the sample. c. The mean level of the hour spent in the office during week 2 is 47.47 hours, with the standard deviation of 17.06. The distribution is slightly negative skew (-0.237), although in an acceptable range suggest that slightly more samples spend more hours in office than the average. The distribution’s value for kurtosis (-1.005) exceeds the acceptance level (value between 1.0…

significant at 10% as well as the MA (2) coefficient. As a result of this insignificance of estimates, we can infer that for this particular model, the random shocks at each point can be interpreted as mutually independent and come from the same distribution. The main difference between MA and AR models is that in MA models a shock affects the values of X only for the current period and q periods in the future; while in the AR models a shock affects infinitely the values of X since affects Xt ,…

An outlier is one who is outside the normal, and defies the odds. I believe that Julia Blackwell meets the criteria of being successful outlier. In her life so far she has been accepted into private school, found her passion, been chosen to represent the Maine council of Girl Scouts at the national convention, been accepted into Colgate College, and has been chosen to represent Maine at the United States Senate Youth Program. Julia is a senior at North Yarmouth Academy, and she is from Woolwich,…
