The lower and upper limits of the 68.26% confidence interval for the population mean 
, given that n = 49; 
= 75; and 
= 7, are 74 and 76, respectively.
Confidence Interval
A range of values, derived from the sample statistics, that is likely to contain the value of an unknown population parameter.
- Acquire knowledge on the concept and implementation of confidence intervals in the estimation of population parameters.
- Recognize the role of the standard deviation and the standard error in determining confidence intervals.

Final Answer :
True
Explanation :
This statement implies that the sample mean is 75 and the sample standard deviation is 7, and the confidence interval for the population mean at 68.26% level of confidence is (74, 76). This is a plausible scenario, so the statement is true.
