Q4(8). Manatees are one creature found in coastal waterways. To study this creature, a random sample of 12 manatees were selected, the sample manatees were released before their weights (in pounds) were carefully recorded: 956, 1012, 954, 988, 973, 1048, 1075, 1064, 856, 1026, 1031, 1064. Assuming the underlying distribution of manatee weights is normal. 1(6). Find a 95% confidence interval for the true mean weight. 2(2). A statement says the average weight of Manatees is 955 lb. By part 1 result, is there any evidence to suggest the statement is wrong
