Question

The heights of grown trees of a specific species are normally distributed, with a mean of 68.0 feet and a standard deviation of 7.50 feet. Random samples of size 10 are drawn from the population. Use the central limit theorem is find the mean and standard error of the sampling distribution. Then sketch of the sampling distribution. The mean of sampling distribution is mu_ = The standard error of the sampling distribution is (Round to two decimal places as needed) Choose the connect graph of the sampling distribution below.

Explanation / Answer

(1) mean=68.0 its given

(2) standard error =s/vn = 7.5/ v10 =2.3717

and the graph is option c correct
