Question 1077018: Previously, 24% 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 68 of 200 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? Use the
α=0.1 level of significance.
I know the null hypothesis is equal to .24 and the alternative is not equal to .24, but what is the Z0 equal to?

alpha=0.1
test statistic is z with |z|>1,645 is the critical value (z0.95)
z=(.34-.24)/sqrt p*(1-p)/n; the denominator is sqrt[.24*.76/200]=0.0302
z=.10/.0302=3.311
reject Ho, p=0.001
