Question
The floor exercise is a commonly shared event between the Women’s and Men’s Artistic Gymnastics programs. Let’s compare the floor exercise scores of the female gymnasts and male gymnasts. To do this, we will consider the 2007, 2011, and 2015 results as sample data.
Individual All-Around Finals
We will first look at the floor exercise scores in the Individual Female All-Around Finals and in the Individual Male All-Around Finals.
i. Find the sample mean and sample standard deviation for the floor exercise scores in the Individual Female All-Around Finals and the Individual Male All-Around Finals.
ii. Construct a 95% confidence interval for the difference in population mean floor exercise scores between female and male gymnasts in the Individual All-Around Finals. (Hint: Use the results of i. and use the t-distribution.)
iii. Using the confidence interval in part iii., can we infer at the 5% significance level that the population mean floor exercise score in the Individual All-Around Finals is different for female gymnasts and male gymnastics?
