Mariulka [41]

Step-by-step explanation:

Mean = 81740

Standard deviation = 4590

Sample size = 15

Alpha level = 1-0.95 = 0.05

Df = 15-1 = 14

Critical value:

alpha/2 = 0.05/2 = 0.05

t0.025

t critical value = 2.145

Margin of error ME

2.145 x 4590/√15

2.145 x 4590/3.873

ME = 2542.09

Confidence interval

Lower CI = mean - ME

= 81740-2542.09

= 79197.91

Upper CI = mean + ME

= 81740+2542.09

= 84282.09

[ 79197.91, 84282.09]

B.

Using excel, exact answer for CI

Lower limit = 79198.142724212173

Upper limit = 84281.8572757827

C.

The assumptions to be made from the population are that

1. Samples are random

2. These samples are gotten from an approximately normal distribution

Charra [1.4K]
 Gross Income of $54,300, Adjustments of $2460, 2 Exemptions of $16,400, and Deductions of $16,500?

Taxable amount = $54,300 - ( $2460 + $16,400 + $16,500 ) = 84,740.
I don't have the list of the tax bracket. The tax bracket of 2016 and 2017 are also different. Just get the tax bracket and multiply the taxable amount.
