You are given the sample mean and the population standard deviation. Use this information to construct the90% and95% confidence intervals for the population mean. Which interval iswider? Ifconvenient, use technology to construct the confidence intervals.A random sample of 34gas grills has a mean price of $636.40. Assume the population standard deviation is $56.40.

The90% confidence interval is __,__(Round to one decimal place asneeded.)

The95% confidence interval is __,__ (Round to one decimal place asneeded.)

Which interval iswider? 90% or 95%?
