In the year 2033, katy perry is a leading traveling nurse. Katy is interested in reducing the mean recovery time for patients after experiencing a serious injury (assume recovery times are normally distributed). Suppose the mean recovery time is presently 8.6 months. Katy takes a random sample of 46 patients that have experienced serious injury to participate in a new treatment program and finds the sample mean is 8.1 months and a sample standard deviation of 1.2 months. Using a = 0.05, answer the following questions. d) Using the appropriate level of confidence, what is the confidence interval? e) What is the interpretation (not your conclusions) of the confidence interval (in the context of the problem) you obtained in part c? f) What is the p value?

Practice Problem #1: The junior high basketball team played ten games. Find the standard deviation for the number of baskets scored by the team for the ten games: 8, 4, 6, 6, 7, 7,9, 4, 8, 5. Follow the steps below to calculate the standard deviation. Step 1: Average the scores in the Score column of the table below in order from the smallest to the largest. Step 2: Find the mean of the data set and place your answer below on Line A. Step 3: Subtract each of the scores from the mean. Record the difference in the Difference From The Mean column in the table below. Be sure to record whether the answer is positive or negative. (i.e.:4-5=-1,7-5%3-2) Step 4: Find the square of each number in the Difference From The Mean column and record the result in the Square of the Difference column (i.e.:(-1) 1) Step 5: The number of items in the data set in labeled n.

7 Confidence interval for a population proportion Twenty years ago, a very famous psychologist specializing in marriage counseling authored book detailing the way in which she believed spouses should communicate. She is now interested in the proportion of all couples who bought her book who stayed together. For a random sample of 200 couples who bought her book, she found that 162 of them stayed together. Based on this, compute a 95% confidence interval for the proportion of all couples who bought her book who stayed together. Then find the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places. (If necessary, consult a list of formulas.)
