Jenny wanted to know if people who exercise regularly eat more apples than people who don’t exercise regularly. She took a simple random sample of six people who exercise. Their standard deviation was 2.00. She then took a new simple random sample of eight people who don’t exercise. Their standard deviation was 1.51. Please calculate the test statistic for this experiment; then state the critical value; then come to a conclusion concerning the null hypothesis; and then state what the implications are concerning exercise and eating apples.
