You must estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures:- 22.4- 36.1- 43.5- 18- 43.8- 27.4- 23.7- 4.9- 26.5Find the 80% confidence interval. Enter your answer as an open-interval (i.e., parentheses) accurate to two decimal places (because the sample data are reported accurate to one decimal place).80% C.I. = (______)Answer should be obtained without any preliminary rounding.
