<u>Step-by-step explanation:</u>
range = 2200 - 300 = 1900
To find standard deviation, we have:
standard deviation = range/4 = = 475
The range rule of thumb estimate for the standard deviation is 475
Given:
Standard deviation, = 475
Margin of Error, ME = 100
= 1 - 0.90 = 0.10
Za/2 = Z0.05 = 1.64

n ≥
n ≥ 60.68
≈ 61
