A teacher was able to find data from 1981 (sample 1) on the amount of time per week, children spend on chores. She believes, on average, children are spending less time per week on household chores today compared to 1981 levels. To test her claim, the teacher gathers data in 2018 (sample 2). Assuming the population variances are equal, you will specify the hypotheses, calculate the test statistic and p-value and make conclusions based off your results.
