A data set includes 109 body temperatures of healthy adult humans for which x 98 .2 degrees F. and s =.62 degrees F.

What is the best point estimate of the mean body temperature of all healthy humans?

1. ThebestpointestimateisF(Typeasintergerordecimal)

What is the confidence interval estimate of the population mean ? Degrees F < < degrees F. (Round to 3 decimals).

Do the confidence interval limits contain 98.6 degrees F? Yes or NO

What does this suggest about the use of 98.6 degrees F as the mean for body temps? (A,B, or C)

1. a This suggests that the mean body temperature could very possibly be 98.6 F.
2. b This suggests that the mean body temperature could be lower than 98.6 F.
3. c This suggests that the mean body temperature could be higher than 98.6 F.
