Suppose a simple random sample of athletes in the NBA heights is taken. There were 28 athletes in the sample with a mean height of 78.4 inches and standard deviation of 2 inches. It has been confirmed through statistical analysis that NBA player heights follows a normal distribution.

a. what parameter are we estimating?

b. Explain the requirements as they relate to the problem

c.What is the point estimate of the parameter?

d.Input the margin of error for a 95% confidence interval for the true average height of NBA players.
Write the equation you used and the numbers .

e. Create and input your interval using your answer in part d.

f.  Interpret your interval. (explanation)

g.Use your interval to respond to the statement that the true average height of NBA players is less than than 78.4. Thoroughly explain why you are responding the way you are.

h. What does the central limit theorem say about the sample distribution of the sample average of basketball player heights for this problem?

please show all work and round to the fourth on all ansers
