The body temperatures in degrees Fahrenheit of a sample of 9 adults in one small town are:
97.9 |
97.6 |
96.3 |
98.3 |
98.7 |
98 |
96.7 |
98.6 |
97.3 |
Assume body temperatures of adults are normally distributed. Based
on this data, find the 90% confidence interval of the mean body
temperature of adults in the town. Enter your answer as an
open-interval (i.e., parentheses)
accurate to twp decimal places (because the sample data are
reported accurate to one decimal place).
90% C.I. =
Answer should be obtained without any preliminary rounding.
However, the critical value may be rounded to 3 decimal places.
