the amount of money rick earned can be solve using the formula:

F = P (1+ i)^n

Where F is the future money

P is the initial money

i is the interest rate

n is the time

F = 1000 ( 1 + 0.04)^10

F = $ 1,480.24

Sally

F = 1000 + (50)(10)

F = $ 1500

So the answer is D

a. The standard error is equal to the standard deviation divided by the square root of the sample size:

SE = (23 ppm)/√18 ≈ 5.42 ppm

b. The t statistic is given by the difference between the true and sample means, divided by the standard error:

t = (192 ppm - 180 ppm)/SE ≈ 2.21

c. The p-value is approximately 0.0204.

d. Since p < 0.05, the difference is significantly different, so we reject the null hypothesis.

e. A type I error might have occurred, since it's possible that the null hypothesis was true, but we ended up rejecting it.
