Question
A data set includes 109 body temperatures of healthy adult humans for whichx-98.2°F and s 0.62°F. Complete parts (a) and (b) below. Click here to view a t distribution table Click here to view page 1 of the standard normal distribution table view page 2 of the a. What is the best point estimate of the mean body temperature of all healthy humans? The best point estimate isF (Type an integer or a decimal.) era ure of all healthy humans o econfidence 3.6 b. Using he sample statistics, construct a 99% confidence interval estimate o the mean boo What does the sample suggest about the use of 98.0°F as the mean body temperature? na m s nt in What is the confidence interval estimate of the population mean ? (Round to three decimal places as needed.) Do the confidence interval limits contain 98.6 F? O Yes O No What does this suggest about the use of 98.6°F as the mean body temperature? 0 A. 0 B. ° C. This suggests that the mean body temperature could be lower than 98.6°F This suggests that the mean body temperature could very possibly be 98.6° This suggests that the mean body temperature could be higher than 98.6°FExplanation / Answer
Mean is 82.5 and s is 0.62
a) best point estimate is the same as mean which is 82.5
b) for 99% confidence, the z value is 2.576
the lower limit is mean-z*s= 82.5-2.576*0.62=80.9029
and upper limit is = mean+z*s= 82.5+2.576*0.62=84.0971
thus it does not contain 98.6
it sugests that the mean temperature could be lower than 98.6 because the highest value of range is 84.0971 so A
