The 99% confidence interval for the population mean is 6± 2.443

<h3>Confidence interval</h3>

The formula for calculating the confidence interval is expressed as:

CI = x± z(s/√n)

GIven the following parameters

x = 6

s = 3

n = 10

z score at 99% = 2.576

Substitute into the formula to have:

CI = 6± 2.576(3/√10)

CI = 6± 2.443

Hence the 99% confidence interval for the population mean is 6± 2.443

Answer:

The main answer: $4.84

Step-by-step explanation:

County A: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!

$75 * 0.0725 = $5.4375

Add the original price and the sales tax.

$75 + $5.4375 = $80.4375

County B: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!

$70 * 0.08 = $5.6

Add the original price and the sales tax.

$70 + $5.6 = $75.6

Then take the difference.

80.4375 – 75.6 = 4.8375

Round to the nearest hundredth: $4.84
