given data are,
sample mean () = 98.9
sample sd (s) = 0.63
sample size (n) = 106
degrees of freedom = (n-1) = (106-1) = 105
t critical value for df = 105, 99 % confidence level , both tailed test be:-
[ from t distribution table ]
the 99 % confidence interval for population mean be:-
the temperature 98.6 suggests that,
the mean body temperature could be higher than 98.6 degree F.
[ because we are 99% confident that population mean body temperature will be in the interval (98.739 , 99.061) ]
