Question

Let

Answer 1

We have Ux =  127.2 ft while we have σx =  1.985 ft

How to solve for the values

The normal distribution =  127.2 ft

The standard deviation = 27.5 ft

The random sample n is given as n = 192 trees.

sd / √n

= 27.5/√192

= 1.985 ft

Hence we have Mx = 127.2 ft

σx =  1.985 ft

127.2 + 2(1.985) = 131.17

127.2 - 2(1.985) = 123.23
