A study was conducted on the number of minutes spent texting by men and women. A sample of 20 men spent an average of 82.3 minutes a day texting with a sample standard deviation of 24.7 minutes, whereas a sample of 27 women spent an average of 101.4 minutes a day texting with a sample standard deviation of 27.3 minutes. Use a 0.10 significance level to test the claim that the average number of minutes that men spent texting a day is less than the average number of minutes that women spent texting a day.
