The average fee in a private school in Georgia is more than $13,000 for one year with σ = $3000. Assume the population is normally distributed. A random sample of 15 private schools in Georgia yielded a mean yearly fee of $14,500. Test using the critical value method if the population mean of the yearly fee in a private school in Georgia is more than $13,000, using α = 0.10.
