A car manufacturing company was interested in the braking ability of two models of cars that they produced. For this purpose, a researcher collected two random samples (one for each model, both samples were of size n. = 64) of measurements of the number of feet necessary to stop from a speed of 40 miles per hour. For each sample, the researcher calculates the mean and the variance of these measurements and obtained 17A = 100; 8,24 = 102 1?}; =109; 323 = 87 The automobile manufacturer is interested in testing whether the two car models have equivalent braking ability. (a) State the appropriate null and alternative hypotheses. (b) Compute the p-value corresponding to the null hypothesis stated in the previous point using the available data. What can you conclude about the null? (c) Construct a 95% condence interval for the difference between the two sample means
