Suppose now that Maria takes a new random sample of a different size.

She computes the resulting 96% confidence interval to be (2.33, 2.75) oz. It is known that the distribution of the amount of ice cream it takes for all Maria's customers to get a brain freeze is symmetric, unimodal, and has a standard deviation of 1.6 oz.

Calculate the sample size used to compute the above confidence interval. Report your answer as a number (no symbols), and round up to the nearest integer (whole) number.

A college admissions office takes a simple random sample of 120 entering freshmen and computes their mean SAT score to be 448. The population standard deviation is 116. Bsed on a 98%confidence interval mean, is it likely that the mean SAT score for entering freshmen is greater than 464? (first construct the 98% confidence interval)

A quality control specialist for a restaurant chain takes a random sample of size 13 to check the amount of soda served in the 16 oz. serving size. The sample mean is 13.30 with a sample standard deviation of 1.54. Assume the underlying population is normally distributed. We wish to construct a 95% confidence interval for the true population mean for the amount of soda served. What is the error bound? (Round your answer to two decimal places.)
