**Statistical Analysis of Collected Data for PSYC 227 Class Project**A student in PSYC 227 class collects data for a class project involving 10 classmates. The project consists of two tasks for each participant:1. Shooting 10 free throws on a standard basketball court and recording the number of successful shots (variable X).2. Completing an obstacle course and recording the time taken (variable Y).The objective is to statistically evaluate the relationship between variables X (number of shots made) and Y (time taken). The student calculates three key statistical metrics:- The sum of squared deviations for X.- The sum of squared deviations for Y.- The sum of cross products between X and Y.The table below provides a detailed breakdown of the calculations:| | \((X - \overline{X})^2\) | \((Y - \overline{Y})^2\) | \((X - \overline{X})(Y - \overline{Y})\) ||------------------------|------------------------|------------------------|----------------------------------------|| **Participant 1** | 3.24 | 15.21 | -7.02 || **Participant 2** | 7.84 | 0.81 | -2.52 || **Participant 3** | 1.44 | 16.81 | -4.92 || **Participant 4** | 10.24 | 4.41 | -6.72 || **Participant 5** | 0.04 | 9.61 | -0.62 || **Participant 6** | 0.64 | 8.41 | -2.32 || **Participant 7** | 3.24 | 15.21 | -7.02 || **Participant 8** | 1.44 | 0.01 | -0.12 || **Participant 9** | 0.04 | 4.41 | -0.42 || **Participant 10** | 0.64 | 3.61 | -1.52 || **SUM** | **28.8** | **78.5**

The accompanying table shows the height and weight of five football players in training camp. The body mass index (BMI) is used to assess the relative amount of fat in a person's body. If w is weight in pounds and h is height in inches, then BMI = 703wh. Some physicians consider your body fat abnormal if your BMI satisfies BMI-23>3. Which of the five players does not have abnormal body fat? does not have abnormal body fat. Player D Player B Player C Player E Player A ..

The data set Pain contains hypothetical data for a clinical trial of a drug therapy to control pain. The clinical trial investigates whether adverse responses increase with larger drug doses. Subjects receive either a placebo or one of four drug doses (1, 2, 3, or 4 units). An adverse response is recorded as Adverse = 'Yes'; otherwise, it is recorded as Adverse = 'No'. The number of subjects for each drug dose and response combination is contained in the variable Count. (a) Construct a contingency table that corresponds to the data set created above. What type of variable is Dose? (B) Compute the sample proportions of adverse responses at each dose level. Do you observe any trend in the proportion of adverse responses with respect to dose level? (C) Conduct a Cochran-Armitage trend test at the 5% significance level to address the interests of the trial.
Suppose you are conducting a paired t test to determine whether or not caffeine has an effect on heart rate. You have a sample of 60 participants and they ingest no caffeine each day for a week. At the end of the week, you measure their heart rates and find the mean. Then, the same 60 participants are given 500mg of caffeine every day for a week and again, at the end of the week you measure their heart rates and find the mean. What would the null hypothesis be for this test?

(a) A university gives credit in first-year calculus to students who pass a placement test. The mathematics department wants to know if students who get credit in this way differ in their success with second-year calculus. Scores in second-year calculus are scaled so the average each year is equivalent to a 77. This year, 21 students who took second-year calculus passed the placement test.

Elaine is interested in determining if men are more satisfied in their jobs than women in the healthcare industry. She administers a job satisfaction questionnaire to 20 men and 20 women working in hospital administration. Her grouping variable is gender and dependent variable is job satisfaction. The job satisfaction scale consists of 8 items measured using a 5-point rating scale. A higher score on this scale would indicate high job satisfaction. The maximum score that can be obtained on the scale is 40. We can assume that job satisfaction scores are normally distributed. Use the appropriate T test with a significance level of 0.05 to test the hypothesis. Research Question Do the mean job satisfaction scores differ for men and women working in the hospital administration department? Hypothesis- The mean job satisfaction scores do not differ for men and women working in the hospital administration department. Write a Results section based on your analysis. Interpret results of…
Use the figure to the right, which shows the percentages of adults from several countries who favor building new nuclear power plants in their country. The survey included random samples of 1051 adults from Country A, 1120 adults from Country B, 1048 adults from Country C, and 1013 adults from Country D. At a=0.05, can you support the claim that the proportion of adults in Country B who favor building new nuclear power plants in their country is different from the proportion of adults from Country C who favor building new nudear power plants in their country? Assume the random samples are independent. Country A 53% Country B 47% Country C 46% OCountry D 34% Identify the claim and state Ho and H- The claim is "the proportion of adults in Country B who favor building new nuclear power plants in their country is different than the proportion of adults from Country C who favor building new nuclear power plants in their country." Let p, represent the population proportion for Country B and…
