Explanation / Answer

Confidence interval = (Sample mean ± Margin error) = (18680, 21046)

a.95% CI means :
We are 95 % confident that the population mean lies between $18680 and $21046(A).

b.Since $19017 falls in the above interval, we may say that No, do not reject $19017 since $19017 is in the interval and it is plausible that the population mean student debt is $19017(D).
