The heights of American men are normally distributed. If a random sample of American men is taken and the confidence interval is

solmaris [256]

Answer:

Step-by-step explanation:

Given the confidence interval of the heights of american heights given as (65.3,73.7);

Lower confidence interval L = 65.3 and Upper confidence interval U = 73.7

Sample mean will be the average of both confidence interval . This is expressed mathematically as $\overline x = \frac{L+U}{2}$

$\overline x = \frac{65.3+73.7}{2}\\\overline x = \frac{139}{2}\\\overline x = 69.5$

Hence, the sample mean is 69.5
