Step-by-step explanation:
The confidence interval for population mean is given by :-
, where
is the sample mean and ME is the margin of error .
Given : The sample mean :
Margin of error :
Then , the range of values (confidence interval) likely to contain the true value of the population parameter will be :-
Hence, the range of values likely to contain the true value of the population parameter =
