If a 0.10 significance level is to be used to test the claim that p 1 less thanp 2, what confidence level should be used? In a large clinical trial, 393,577 children were randomly assigned to two groups. The treatment group consisted of 195,930 children given a vaccine for a certaindisease, and 35 of those children developed the disease. The other 197,647 children were given a placebo, and 115 of those children developed the disease. Considerthe vaccine treatment group to be the first sample.

In general, when dealing with inferences for two population proportions, which two of the following are equivalent: confidence interval method; P-value method;critical value method?P-value method and critical value methodare equivalent, in that they will always lead to the same conclusion. Both of these methods use a standarddeviation based on the assumption that the two population proportions are equal, whereas the other method uses a standard deviation based onestimated values of the population proportions.c.

Several years ago, 37%of parents with children in grades K-12 were satisfied with the quality of education the students receive. A recent poll found that 486 of 1,165 parents with children in gradesK-12 were satisfied with the quality of education the students receive. Construct a 95% confidence interval to assess whether this represents evidence that parents' attitudes toward the quality of education have changed. What are the null and alternative hypotheses?
