Answer: C) 133
Step-by-step explanation:
The formula to find the sample size is given by :-

, where z* = Critical z-value
= Population standard deviation for prior study.
E= Margin of error.
As per given , we have
E= 5
The critical z-value for 90% confidence level is 1.645.
Substitute al;l the value sin the above formula , we get




Hence, the minimum sample size needed is 133.
Thus , the correct answer is : C) 133
To find the answer, you must subtract 1632 and 74, which results in 1558, so the Transamerica Pyramid is 1558 ft tall.
I hope this helps.
When you plug the equation into a graphing calculator the x-intercept is -5
Or you can set the equation equal to 0 and solve for x.
