10. You want to construct a 95% confidence interval for the proportion of all Stetson MATH 125Q students who have had a prior statistics class. A random sample of 18 Stetson MATH 125Q students showed that 6 of them had a prior statistics curse. Use the sample to construct the confidence interval. State the point estimate and the margin of error and give the interval. Write a sentence of interpretation for the interval. 1 1. You want to construct a 99% confidence interval for the amount of time that MATH 125Q students plan to spend outside of class working on the class. A random sample of 18 Stetson MATH 125Q students gave the following responses to that question (in hours). 6 5 2 4 5 3 2.5 5 10 4 5 4.5 4.5 11 2.5 3.5 3 4 a. What is the sample mean? b. What is the margin of error for the confidence interval? Assume o = 5 hours. c. What is the confidence interval? Write a sentence of interpretation
