Statistics gathered on delay at a machine on 26 independently different days yielded a sample mean of 3.0 minutes and a sample standard deviation of 1.3 minutes. Suppose 12 independent simulation runs were conducted on the new machine, giving a sample mean of 2.3 minutes and a sample standard deviation of 1.4 minutes. (i)Construct a 95% confidence interval for the difference between the two machines. (ii) Interpret the results in part (i) above

Part 1 of 3: The age when smokers first start from previous studies is normally distributed with a mean of 13 years old with a population standard deviation of 1.9 years old. A survey of smokers of this generation was done to estimate if the mean age has changed. The sample of 32 smokers found that their mean starting age was 14.3 years old.

A simple random sample of size n = 40 is drawn from a population. The sample mean is found to be x = 121.2 and the sample standard deviation is found to be s = 12.6. Construct a 99% confidence interval for the population mean. The lower bound is (Round to two decimal places as needed.) The upper bound is . (Round to two decimal places as needed.)
"A company produces resistors by the thousands, and Gerry is in charge of quality control. He picks 26 resistors at random as a sample, and calculates the sample mean x = 7.268 kOhms and sample standard deviation S = 0.2142 kOhms. Calculate the confidence interval as a (+/-) value to 65% confidence level."

The electric cooperative needs to know the mean household usage of electricity by its non-commercial customers in kWh per day. They would like the estimate to have a maximum error of 0.14 kWh. A previous study found that for an average family the variance is 4.84 kWh and the mean is 19.1 kWh per day. If they are using a 80% level of confidence, how large of a sample is required to estimate the mean usage of electricity?
