Given:
Sample proportion = 85% = 0.85.
Confidence level (CL) = 90%.
Confidence interval (CI)

We want the confidence interval to be 5% or 0.05. Therefore

Because this number is less than 1, a default sample size of 30 (for the normal distribution) is recommended.
Answer: 30
32^(-1/5)
1/32^(1/5)
^1/5 means 5√32 = 2
so the answer is 1/2 or 0.5
Given:
The last year sales = $288,000,000
Company increased its sales from last year to this year by 34%.
To find:

This year's sales 



Therefore, this year's sales were 386 million dollars or $386,000,000.
