You must estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures:
26.6 |
58.4 |
47.5 |
62.2 |
33 |
49.3 |
40.3 |
Find the 98% 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).
98% C.I. =
Answer should be obtained without any preliminary rounding.
First we will calculate the sample mean and sample variance:
The sample mean is :
The 98% confidence interval is calculated as:
Confidence Interval: (29.964,60.696)
