Solve the problem.
-A $99 \%$ confidence interval (in inches) for the mean height of a population is $65.3 < \mu < 66.9$ . This result is based on a sample of size 144 . Construct the $95 \%$ confidence interval. (Hint: you will first need to find the sample mean and sample standard deviation) .

A) $65.6$ in $< \mu < 66.6$ in.
B) $65.3$ in $< \mu < 66.9$ in.
C) $65.5$ in $< \mu < 66.7$ in.
D) $65.2$ in $< \mu < 67.0$ in.
