Answer: 505
Step-by-step explanation:
The formula to find the sample size n , if the prior estimate of the population proportion (p) is known:
, where E= margin of error and z = Critical z-value.
Let p be the population proportion of crashes.
Prior sample size = 250
No. of people experience computer crashes = 75
Prior proportion of crashes 
E= 0.04
From z-table , the z-value corresponding to 95% confidence interval = z=1.96
Required sample size will be :
(Substitute all the values in the above formula)
(Rounded to the next integer.)
∴ Required sample size = 505
Answer:
Multiply by 6 on both sides
X-8 = 27
add 8 to both sides
X = 35
Hope this helps
Double-checking
35 - 8 = 27
27 / 6 = 4.5
35 = X is the answer
Hope this helps
