You must estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures:
51.4
38.7
44.9
26.2
40.3
23.3
43.1
24.2
24.9
35.9
30.5
29.3
Find the 90% 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).
