7. A past study claims that adults spend an average of 18 hours a week on leisure activities. A researcher wanted to test this claim. He took a sample of 10 adults and asked them about the time they spend per week on leisure activities. Their responses (in hours) were as follows 14; 25; 22; 38; 16; 26; 19; 23; 41; 33 Assume that the time spent on leisure activities by all adults is normally distributed. Using the 5% significance level, can you conclude that the claim of earlier study is true?
