Twenty years ago, 52% 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 291 of
800 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 α=0.01 level of significance.
a. Because np01−p0=_____ is [>,<,=,≠] 10, the sample size
is [>,<] 5% of the population size, and the sample [can be
reasonably assumed to be random is given to be random, is given to
not be random, cannot be reasonably assumed to be random] the
requirements for testing the hypothesis ____ satisfied.
b. H0 [ ] [ ] [ ] versus H1 [ ] [ ] [ ]
c. Now find p ̂
d. Determine the statistic, z0
e. Find the P-value
f. State the conclusion of the hypothesis test
