helped me with porting these data from the tilt sensor into their DynaTIm data sorter. Which could handle the data flow and maintain a graphic user visual towards the parameters. For comparison we also connected the tree to a DynaTIm sensor from RinnTech. This process yielded us with some amazingly accurate values to the degree of 10000th. Even though the millisecond part of the code was a software oriented one and had minor calibration issues, our sensors worked just fine. They were actually…

decisions. The various preferences should be weighted against each other and a percent importance should be applied to that characteristic as its weighting factor. All weighting factors should sum to 100%. A baseline technology should be selected with which to compare all the other technologies or solutions. A variance factor between the baseline and the alternative is assigned and put in the appropriate cell. Commonly -9, -3, -1, 0, 1, 3, 9 are the assigned variance levels. The assigned…

1. What is an exact probability model for the number of automobile accidents over the past year for the 50 medical interns? (Note: The 11 reported accidents include both police-reported and non-police-reported accidents). Answer:- Fixed Proportion = .065 Number of interns involved in accident last year = total number of interns*.065. n = .065*It where n denoted interns in an accident and It denotes the total number of interns. P(n) = ItCn*.065^n*.935^(It-n)......from .binomial probability…

The second dataset ,named dataset2 contains Market Basket retails for sale data from one of china's markets unknowns. It contains 11040.0 transactions database, it has over 12 items and most of the transactions contain between 7 and 11 items. The third dataset ,named dataset 3 contains the retail list of medications from a pharmacy data from an anonymous china retail store. It contains 13454.0 transactions over 20 items and most of the transactions contain between 9 and 15 items. The fourth…

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…

I learned a lot about my positivity over the past two weeks of recording my data. My average from the past two weeks was .82 which is not a good ratio. My average negativity score was 2.7, and my average score positivity was 2.3. My best positivity ratio was 6 and this will be the day I reconstruct and find out where I am most positive. In these past two weeks I had several exams and some quizzes which could be why ratio was so low. I was overwhelmed with stressed the first week I was…

A true experiment, taking place in a natural setting to determine the causal relationship between two things, has many important factors to account for. The experiment administrator must first consider the independent and dependent variables, pre testing and post testing of subjects, and the split between experimental and control groups. These two groups must be equivalent, and the experimental group must be exposed to the treatment, or the independent variable. My true experiment to test…

The null hypothesis stated that there is no difference in genetic variability or heterozygosity between the wild and founding populations. Based on the statistical Chi-square test comparison of genetic diversity between populations, the null hypothesis is valid and should not be rejected. The SPSS statistical results yielded a chi-square value of 0.773a and a P-value of 0.942 (Table 2). 0.942 is greater than 0.05, which means that statistically, there is no significant difference between the two…

Experiments allow researchers to intervene and change behavior. Experiments also allow researchers to examine more than two variables at a time. Correlation studies, on the other hand, allow researchers to observe patterns that are not manipulated as they are in experiments. Correlations studies also only allow two variables to be observed at one time so that “the direction and strength for the association between the two variables” (Noba, 2014, p. 37) can be determined. As stated above,…

Reason for Referral: Shelby is a fifteen-year-old, female that is referred to the examiner by her mother, Natasha G. She has referred Shelby because she needs assistance in the area of mathematics. She is currently taking Advanced AC and DC Circuits for her track in the Engineering program at her school and she still needs help strengthening her Calculus skills. In her Advanced AC and DC Circuits class, she maintains an A letter grade. However, Shelby and her mother would like assistance to…
