[20pts] In 2005, 45% of parents with children in high school felt it was serious problem that high school students were not being taught enough math and science. A recent survey found that 52 out of 120 parents with children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did in 2005? Conduct a hypothesis test at 5% significance level.

a.What are the null and alternative hypotheses? What is the type of the test (left, right, or two tailed)?

b. Compute the test statistic (Round intermediate steps to 4 decimal places and round to 2 decimal places.)

c. Use the z table to find the P-value

d. What is her conclusion? Show detailed comparison and explanation.
