We have Ux = 127.2 ft while we have σx = 1.985 ft
<h3>How to solve for the values</h3>
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
