1.In a clinical trial, 27 out of 847 patients taking a prescription drug daily complained of flu like symptoms. Suppose that it is known that 2.6% of patients taking competing drugs complain of flu like symptoms.

(a)State the null and alternative hypotheses.

(b)Find the test statistic Z0

(c)Find the P-value.

(d)Is there sufficient evidence to conclude that more than 2.6% of this drug's users experience flu like symptoms as a side effect at the =0.05 level of significance?

2.Twenty years ago, 49% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 237 of 750 parents of 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 twenty years ago? Use the

=0.01 level of significance.

(a)State the null and alternative hypotheses.

(b)Find the test statistic Z0

(c)Find the P-value.

(d)State your conclusion.
