Question

A) what is the best point estimate of the mean body tempature of all healthy humans? ...The best point estimate is 98.3 feherin
B) using the samplestastics, construct a 99% confidence interval estimate of the mean body tempature of all healthy humans. Do th confidence interval limits contain 98.6 feherin? What does the sample suggest about the use of 98.6 feherin as the mean body tempature ?
What is the confidence interval estimate of the population mean u? ?feherin<u< ?feherin (Round to three decimal places as needed) cld: Adrianna Brodie 1 Score: 0 of 2 pts HW Score adult humans for which x-98 3 F and s 054°F. Complete parts (a) and (b) below contain 98 6 )What does the sample suggest about the use of 98 6°F as the mean body temperature? What is the confidence interval estimate of the population mean ?

Explanation / Answer

Note that              
Margin of Error E = z(alpha/2) * s / sqrt(n)              
Lower Bound = X - z(alpha/2) * s / sqrt(n)              
Upper Bound = X + z(alpha/2) * s / sqrt(n)              
              
where              
alpha/2 = (1 - confidence level)/2 =    0.005          
X = sample mean =    98.3          
z(alpha/2) = critical z for the confidence interval =    2.575829304          
s = sample standard deviation =    0.54          
n = sample size =    109          
              
Thus,              
Margin of Error E =    0.133228639          
Lower bound =    98.16677136          
Upper bound =    98.43322864          
              
Thus, the confidence interval is              
              
(   98.16677136   ,   98.43322864   ) [ANSWER]

***********************************

As we can see, NO, IT DOES NOT CONTAIN 98.6. [ANSWER]
