2. A researcher conducts a study examining the effectiveness of a group exercise program at an assisted living facility for elderly adults. One group of residents is selected to participate in the program, and a second group serves as a control. After 6 weeks, the researcher records a combined score measuring balance and strength for each individual. The data are as follows: Control n = 10 M = 12 SS = 120.5 Exercise n = 15 M = 15.5 SS = 190.0 Conduct the four steps for hypothesis testing and label a. Use a two-tailed test with a = .05. each step: Step1, Step 2, Step 3, and Step 4. b. Calculate Cohen's d. c. Are the data sufficient to conclude that thier is a significant difference?

A healthcare provider monitors the number of CAT scans perfomed each month in each of its clinics. The most recent year of data for a particular clinics follows (the reported variable is the number of CAT scans each month expressed as the number of CAT scans per thousand members of the health plan): 2.31, 2.09, 2.36, 1.95, 1.98, 2.25, 2.16, 2.07, 1.88, 1.94, 1.97, 2.02. Find a two-sided 95% confidence interval for the standard deviation. What should you do to address any reservations about this confidence interval? Round your answers to two decimal places (e.g. 98.76).

You are a manager for Company ABC and decide to compile data and analyze your employees’ level of satisifaction. You create a survey to ask each employee to rate their level of satisfaction working at Company ABC. Table 1 shows data of 15 people employees that responded to your survey. Each of the employees have the same job title: Sales Representative. The data set includes variables regarding an employee ID, gender, ethnicity, region, pay rate, employee satisfaction rating. Each employee was asked to rate their level of satisfaction working at Company ABC. A composite score from 0 (lowest) to 5 (highest) is shown as the data variable employee satisfaction. Table 1: Employee Data on 15 Sales Representatives at Company ABC
A team of pharmacists was researching two sleeping pills they were developing. 20 individuals took part in the study and they were randomly divided into two groups and one group received sleeping pills 1 and the other group sleeping pills 2. The pharmacists then measured how long the individuals slept after ingestion. The data can be seen below: SLEEPING MEDICINE 1 SLEEPING MEDICINE 2 9.2 6.8 7.4 6.2 10.1 8.1 6.8 7.2 9.1 5.8 8.2 8.8 9.2 6.2 8.8 7.1 7.6 7.3 8.8 6.9 Let us now assume that the assumptions that need to apply can be used in a study such as this to confirm the efficacy of the drugs. Examine with an appropriate hypothesis test whether there is a difference in mean sleep duration after taking the two drugs. In the event that you need to check whether the distribution in the two groups can be assumed to be the same, it is sufficient to use the rule of thumb to determine this. Sleep duration can be assumed to follow a normal distribution. Use a = 0.05. Show all six steps. Please…
