Asample of 106 healthy adults have a mean body temperature of 98.2, and a standard deviation of 0.62. construct a 99% confidence interval estimate of the mean body temperature of all healthy humans. group of answer choices ( 98.04, 98.36 ) ( 97.54, 97.95 ) ( 97.84, 98.12 ) ( 97.82, 98. 15 ) ( 97.95, 98.15 )

Step-by-step explanation:

Given : Sample size of healthy adults: n= 106

Degree of freedom = df =n-1 = 105

Sample mean body temperature  :

Sample standard deviation :

Significance level ;

∵ population standard deviation is unknown , so we use t- critical value.

Confidence interval for the population mean :

Using t-distribution table , we have

Critical value for df = 105 and =

A 99% confidence interval estimate of the mean body temperature of all healthy humans will be :

Hence, a 99% confidence interval estimate of the mean body temperature of all healthy humans =

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
