State hypotheses, identify claim, find critical values compute test value, make decision, summarize, after that construct a 95% confidence interval for the true mean number of paid working hours at home, compare results

Working at Home Workers with a formal arrangement with their employer to be paid for time worked at home, worked an average of 19 hours per week. A random sample of 11 mortgage brokers indicated that they worked a mean of 23.6 hours per week with a standard deviation of 6.5 hours. At a = 0.05, is there sufficient evidence to conclude a difference? Construct a 95% confidence interval for the true mean number of paid working hours at home. Compare the results of your confidence interval to the conclusion of your hypothesis test and discuss the implications
