In a recent survey of gun control laws, a random sample of 564 women, 313 favored stricter gun control laws. In a random sample of 588 men, 307 favored stricter gun control laws. Can it be concluded at the .05 level of significance that a lower proportion of men favor stricter gun control than women?

Construct the indicated confidence interval for the difference in proportions. Assume that the samples are independent and that they have been randomly selected. In a random sample of 300 women, 70% favored stricter gun control legislation. In a random sample of 200 men, 56% favored stricter gun control legislation. Construct a 98% confidence interval for the difference in the proportions of women and men who favor stricter gun control legislation.

Historically, the percentage of residents of a certain country who support stricter gun control laws has been 52%. A recent poll of 916 people showed 522 in favor of stricter gun control laws. Assume the poll was given to a random sample of people. Test the claim that the proportion of those favoring stricter gun control has changed. Perform a hypothesis test, using a significance level of 0.05. State the null and alternative hypotheses. H 0: The population proportion that...

For the following test, assume that the two samples are independent simple random samples selected from normally distributed populations and that the population standard deviations are equal (1 = 02) so that the standard error of the difference between means is obtained by pooling the sample variances. A researcher was interested in comparing the amount of time spent studying baboons by women and men from a group of anthropologists. Independent simple random samples of 32 women and 30 men were...

Name: Chapter 9: 01. Use the traditional method to test the given hypothesis. Assume that the samples are independent and that they have been randomly selected. In a random sample of 500 people aged 20-24, 22% were smokers. In a random sample of 450 people aged 25-29, 14% were smokers. Test the claim that the proportion of smokers in the two age groups is the same. Use a significance level of 0.01.
