The confidence interval for population mean is given by :-
, where n= sample size
= sample mean.
z*= Critical value.
= population standard deviation.
As per given , we have
n= 50
Also, we know that the critical value for 95% confidence interval : z*= 1.96
Then, the 95% confidence interval (CI) to estimate the true average score of golfers on this particular course will be :
(substitute all the value in the above formula.)
Hence, the correct option is c.
