Answer:

7

you can alway convert the fraction to a decimal so it'll be

1) To find the confidence interval
the sample mean x = 38 σ = 9; n = 85;
The confidence level is 95% (CL = 0.95) CL = 0.95
so α = 1 – CL = 0.05
α/2 = 0.025 Z(α/2) = z0.025
The area to the right of Z0.025 is 0.025 and the area to the left of Z0.025 is 1 – 0.025 = 0.975
Z(α/2) = z0.025 = 1.645 This can be found using a computer, or using a probability table for the standard normal distribution.
EBM = (1.645)*(9)/(85^0.5)=1.6058 x - EBM = 38 – 1.6058 = 36.3941 x + EBM = 38 + 1.6058 = 39.6058
The 95% confidence interval is (36.3941, 39.6058).
The answer is the letter D
The value of 40.2 is within the 95% confidence interval for the mean of the sample

2) To find the confidence interval 
the sample mean x = 76 σ = 20; n = 102; 
The confidence level is 95% (CL = 0.95) CL = 0.95
so α = 1 – CL = 0.05
α/2 = 0.025 Z(α/2) = z0.025
The area to the right of Z0.025 is 0.025 and the area to the left of Z0.025 is 1 – 0.025 = 0.975
Z(α/2) = z0.025 = 1.645 This can be found using a computer, or using a probability table for the standard normal distribution.
EBM = (1.645)*(20)/(102^0.5)=3.2575 x - EBM = 76 – 3.2575 = 72.7424 x + EBM = 76 + 3.2575 = 79.2575 
The 95% confidence interval is (72.7424 ,79.2575).
The answer is the letter A and the letter D
The value of 71.8 and 79.8 are outside the 95% confidence interval for the mean of the sample

In February, Mr. Williams opened a checking account and made deposits of $949, $1419, $1598, and $1289. He also wrote checks for

kkurt [141]

Based on the deposits and written checks, Mr. Williams' account balance at the end of the month is $3,606.

<h3>What is the account balance?</h3>

The account balance represents the net amount remaining in the account after subtracting the checks from the deposits.

Other factors are taken into account for determining the account balance, including direct credits and debits like bank transfers and charges for bank services.

Thus, the account balance can be utilized by Mr. Williams for his banking transactions in March.

<h3>Data and Calculations:</h3>

Total Deposits = $5,255 ($949 + $1419 + $1598 + $1289)

Total checks = $1,649 ($84 + $167 + $352 + $384 + $662)

Account balanced = $3,606 ($5,255 - $1,649)

Thus, based on the deposits and written checks, Mr. Williams' account balance at the end of the month is $3,606.
