The data is off to the side. Thank you!

DM Honey 12 15 10 13 10 A W O - O N D J J J A DOA 2. (9 points) 14 Is honey a cough remedy? Children who were ill with an upper respiratory tract infection and their parents participated in a study to test the folk remedy. Parents were instructed to give their sick child a dosage of liquid "medicine" prior to bedtime. Unknown to the parents, some were given a dosage of dextromethorphan (DM) - an over-the-counter cough medicine - while others were given a similar 10 dosage of honey. Parents then rated their children's symptoms score was determined for each child. The 12 data (improvement scores) for the 34 children in the DM dosage group and the 35 children in the honey dosage group are collected and stored in the data file Hcough. 6 Assume that the improvement scores are normally distributed, and two population variances are 8 12 unknown but assumed equal. 12 12 12 a. Use Excel's Data Analysis to get the printouts of the descriptive statistics for the improvement 4 scores for each group. Using the printouts from part a, find the two sample standard deviations. Then compute the 12 pooled estimate of the population standard deviation. 13 C. Using the printouts from part a and the pooled estimate of the population standard deviation from part b to construct a 95% confidence interval for the difference in mean improvement 10 scores between two groups. 13 Do the data support the statement "Honey may be a preferable treatment for the cough and 9 13 sleep difficulty associated with child upper respiratory tract infection"? Conduct the test at the 6 5% significance level. Use Excel's Data Analysis to get the test results for the test in part d. In Data Analysis, you use 6 12 "t-Test: Two-Sample Assuming Equal Variances". The value for "Hypothesized Mean Difference" 15 10 in Excel should be 0. 14 f. Use the results in part e to conduct the test in part c at the 1% significance level with the p-value 10 approach. 12
