e heights of people in a certain population are normally distributed with a mean of 68 inches and a standard deviation of 3.8 inches. Determine the sampling distribution of the mean for samples of size 43.

   

Exactly normal.

Mean = 68 inches.

Standard deviation = 0.09 inches.

   

Approximately normal.

Mean = 68 inches.

Standard deviation = 0.09 inches

   

Exactly normal.

Mean = 68 inches.

Standard deviation = 0.58 inches.

   

Exactly normal.

Mean = 68 inches.

Standard deviation = 3.8 inches.
