Answer:
Step-by-step explanation:
For this case we have the following data given:
2.3 3.1 2.8
1.7 0.9 4.0
2.1 1.2 3.6
0.2 2.4 3.2
Since the data are assumedn normally distributed we can find the standard deviation with the following formula:
And we need to find the mean first with the following formula:
And replacing we got:
And then we can calculate the deviation and we got:
The answer is:
(null hypothesis) u=2.7; Ha(alt hypothesis): u<2.7
Answer: 3
Step-by-step explanation:
Answer: The total amount that Paul will end up paying is $1441
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the loan.
P represents the principal or amount taken as loan
R represents interest rate
T represents the duration of the loan in years.
From the information given,
P = 1310
R = 2%
T = 5 years
I = (1310 × 2 × 5)/100 = $131
The total amount that Paul will end up paying is
1310 + 131 = $1441
