A study found that a​ student's GPA,​ g, is related to the number of hours worked each​ week, h, by the equating g= -0.0006h^2 + 0.016h +3.02. Estimate the number of hours worked each week for a student with a GPA of 2.17

Asimple random sample of size nequals14 is drawn from a population that is normally distributed. the sample mean is found to be x overbar equals 70 and the sample standard deviation is found to be sequals13. construct a 90% confidence interval about the population mean
