Assume that a sample is used to estimate a population mean . Find the 90% confidence interval for a sampleof size 65 with a mean of 80.6 and a standard deviation of 9.4. Enter your answer as an open-interval (i.e.,parentheses) accurate to one decimal place (because the sample statistics are reported accurate to onedecimal place).90% C.I. -Answer should be obtained without any preliminary rounding. However, the critical value may be rounded todecimal places.
