Mr. Velasco wanted to know the average weight (in kilos) of students at LAO University. He took a random sample of 100 students and discovered that their average weight is 58 kg. The population standard deviation is 0.75 kg. Construct a 99% confidence interval for the mean weight of students in the University. 1. Researchers are interested to estimate the mean cholesterol level of a particular variety of monkey. Researchers would like their estimate within 1 mg/dl of the monkey's blood at 99% confidence level. Previous study suggests a standard deviation of 5.5 mg/dl. Obtaining monkeys is expensive and time consuming. What is the minimum number of monkeys would they need to generate satisfactory estimate
