Catapult Exercise Data Analysis: Using the catapult exercise data sets from Chapter 4, conduct a hypothesis test of the equality of means and variance of the two different times the catapult was shot. Document the significance probabilities.

From sampled data, note the distribution used when

(a) Calculating the confidence interval on the mean

(b) Calculating the confidence interval on the standard deviation

(c) Comparing two sampled variances
