A what is the best point estimate of the mean body tempature

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 ?

Solution

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]
