Conduct a full hypothesis test and determine if the given claim is supported or not supported at the 0.05 significance level. Round all amounts and standard scores to two decimal places. In one city, the average amount of time that tenth dash graders spend watching television each week is 21.8 hours. The principal of a local high school believes that at his school, tenth-graders watch less television. For a sample of 32 tenth dash graders from the high school, the mean amount of time spent watching television per week was 19.6 hours. Test whether the claim that the mean amount of time spent watching television per week for all tenth dash graders at the high school is less than the city average of 21.8 hours is supported or not supported. Assume that sigma equals 7.2 hours. Question content area bottom Part 1 not supported supported
