7. Sampling Methods and Sampling Distributions a) A student in public Administration wants to determine the mean amount members of the city council earn. The error in estimating the mean is to be less than $100 and 95 a percent level of confidence. The student found a report by the Department of labor that estimated the standard deviation to be $1,000. What is the required sample size? 5 points Confidence Interval b) Suppose we would like to calculate a 90% confidence interval for the mean weight of a certain species of turtle. Suppose we collect a simple random sample with the following information the sample mean is 85 with a population standard deviation of 5.5 from a sample size of 35. Determine the confidence interval.
