Question 1185494: The high temperatures (in degrees Fahrenheit) of a random sample of 5 small towns are:
98
98.8
98.6
96.9
99.6

Assume high temperatures are normally distributed. Based on this data, find the 98% confidence interval of the mean high temperature of towns. 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).
98% C.I. =

Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.

mean is 98.38
s=1.006
98% half t-interval is 3.747 (0.99,ddf=4)*1.006/sqrt(5)=1.686
(96.7 deg, 100.1 deg)
