A study done in 1997 showed that 4.7% of mothers smoked cigarettes during their pregnancy. An obstetrician feels that this percentage is higher now. To test this, the obstetrician takes a sample of 150 mothers and fınds that 9 of them smoked during their pregnancy. Test the obstetrician's claim at the a=0.05 level of significance.

Twenty years ago, 51% 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 309 of 900 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 a= 0.01 level of significance. Because npo (1- po) = 243.5 > 10, the sample size is less than 5% of the population size, and the sample is given to be random, the requirements for testing the hypothesis are satisfied. (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho: 51 versus H1: 51 (Type integers or decimals. Do not round.) Find the test statistic. Zo = 1.96 (Round to two decimal places as needed.) Find the P-value. P-value = .025 (Round to three decimal places as needed.) Determine the conclusion for this hypothesis test. Choose the…

Twenty years ago, 53% 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 327 of 900 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 a = 0.01 level of significance. Because npo (1-Po) =O > 10, the sample size is less than 5% of the population size, and the sample can be reasonably assumed to be random, the requirements for testing the hypothesis satisfied. are (Round to one decimal place as needed.)
