MATH 110 Module 8 Exam Latest Updated 2022. Answer the following questions: 1. Multiple choice: Which equation would you use to solve this problem? A. B. C. D. 2. List the values you would insert into that equation. 3. State the final answer to the problem We see that 90% confidence corresponds to z=1.645. Notice that the sample sizes are each greater than 30, so we may use eqn. B: This study source was downloaded by from CourseH on :00:42 GMT -05:00 So, the interval is (.03065,.12935). In certain hospital, nurses are required to constantly make rounds to check in on all of the patients. The nursing supervisor would like to know if there is a difference between the number of rounds completed per shift by the nurses on the day shift compared to the nurses on the night shift. So, the nursing supervisor checks the records of 70 day shift nurses and finds that they complete an average (a mean) of 30 rounds per shift with a standard deviation of 4.6 rounds per shift. The nursing supervisor also checks the records of 84 night shift nurses and finds that they complete an average (a mean) of 25 rounds per shift with a standard deviation of 5.7 rounds per shift. a) Find the 90% confidence interval for estimating the difference in the population means (µ1 - µ2). b) Can you be 90% confident that there is a difference in the means of the two populations?
