Hey There!:

Sample Mean = 4.4823

SD = 0.1859

Sample Size (n) = 7

Standard Error (SE) = SD/root(n) = 0.0703

alpha (a) = 1-0.99 = 0.01

t(a/2, n-1 ) =  3.7074

Margin of Error (ME) =  t(a/2,n-1)x SE = 0.2606

99% confidence interval is given by:

Sample Mean +/- (Margin of Error)

4.4823 +/- 0.2606 = (4.222 , 4.743)

Hope this helps!

Liula [17]

Incomplete question. However, I answered based on the information.

Explanation:

We can determine which Credit card is best in terms of its interest rate by comparing both rates monthly:

Credit card A

<u>APR for the First 3 months:</u>

4.1% / 360 days = 0.009% x 30 = <u>0.27% </u>per month for the first 3 months.

<u>APR for Next 9 months:</u>

15.7% / 360 days = 0.04361% x 30 = <u>1.308% </u>per month for the next 9 months.

Credit card B:

<u>APR the First 3 months</u>

4.2% / 360 days = 0.011% x 30 = 0.33% per month for the first 3 months

<u>Next 9 months:</u>

15.5% / 360 = 0.04305% x 30 = <u>1.291%</u> per month for the next 9 months

Hence, we can conclude,

  • For the first 3 months, Credit Card A is best because it offers lower interest charges.
  • For the next 9 months, Credit Card B is best because it offers lower interest charges.

alexgriva [62]
First, we add up all the benefits that Gerome Houser gets from his job. That is,
                       $1,755 + $3,898 + $2,898 +$2,098 +$1,404 = $12,053
Then, we divide this amount by his annual salary and multiply the quotient by 100% to get the answer. 
                        ($12,053 / $45,623) x 100% = 26.4%
Therefore, Gerome Houser's rate of benefits is approximately 26.4%.
