According to a government agency, the average workweek for an adult in July 2018 was 34.7 hours. Assume the population standard deviation for the number of hoursworked per week is 5.0 hours. A random sample of 40 adults worked an average of 35.5 hours last week.a. Do the results from this sample support the claim by the government agency?b. Identify the symmetrical interval that includes 82% of the sample means if the true population mean is 34.7 hours per week.a. Do the results from this sample support the claim by the govermment agency? Consider a probability of less than 0.05 to be small.The probability that the sample mean will be greater than 35.5 hours is. The resultsupport the claim by the government agency that the mean is 34.7 hoursbecause this probability isV 0.05.(Type an integer or decimal rounded to four decimal places as needed.)b. The lower bound of the symmetrical interval is(Type integers or decimals rounded to two decimal places as needed.)and the upper bound is.

. Pyramid Lake is on the Paiute Indian Reservation in Nevada. The lake is famous for cutthroat trout. Suppose a friend tells you that the average length of trout caught in Pyramid Lake is ? = 19 inches. However, the Creel Survey reported that of a random sample of 49 fish caught, themean length was ?̅= 18.5 inches, with estimated standard deviation ? = 3.2 inches. Do these data indicate that the average length of a trout caught in Pyramid Lake is less than ? = 19 inches? Use ? = 0.05.a. Do we use a Normal or a Student’s t- distribution? Explain. How many degrees of freedom do we use?b. What are the hypotheses?
