The parent association at a local high school believes that the amount of time spenton homework by students at the school, on average, is more than the school's policyof an average of 30 minutes of homework per class. To test this claim, theadministrators selected a random sample of 50 students, calculated the amount oftime each student spent on homework per class, and tested the hypotheses listedhere:Ho : μ - 30H : μ > 30Where = the mean number of minutes spent on homework, per class, for all studentsin the school. The mean number of minutes spent on homework, per class, for thestudents in the sample was = 34. 7 minutes and the standard deviation10. 4 was minutes. The administrators performed a significance test andSF =obtained a P-value of 0.0012. Based on the P-value, what conclusion would youmake?

In an article in the Journal of Advertising, Weinberger and Spotts compare the use of humor in television ads in the United States and in the United Kingdom. Suppose that independent random samples of television ads are taken in the two countries. A random sample of 400 television ads in the United Kingdom reveals that 142 use humor, while a random sample of 500 television ads in the United States reveals that 122 use humor. a) Set up the null and alternative hypotheses needed to determine whether the proportion of ads using humor in the United Kingdom differs from the proportion of ads using humor in the United States. b) Test the hypotheses you set up in part a by using critical values and by setting a equal to .10, .05, .01, and .001. How much evidence is there that the proportions of U.K. and U.S. ads using humor are different?. Please do this stepwise and explanation and also dont do handwritten or skip please!! I will like.
In analyzing the consumption of cottage cheese by members of various occupational groups, the United Dairy Industry Association found that 326 of 837 professionals seldom or never ate cottage cheese, versus 220 of 489 white-collar workers and 522 of 1243 blue-collar workers (Sheet 53). Assuming independent samples, use the 0.03 level in testing the null hypothesis that the population proportions could be the same for the three occupational groups.

31% of all pygmy softshell toises have stripes on their shells. A herpetologist in Cititon collects a sample of 28 pygmy softshell tortoises and finds that 8 of them have stripes on their shells. Is there enough evidence to conclude, at a significance of alpha=0.05, that the proportion of pygmy softshell tortoises in Cititon with stripes on their shells is less than 31%? What is the claim? What is the null hypothesis? What is the alternative hypothesis? What is the test statistic? What is/are the critical value(s)? Do we reject the null hypothesis? What conclusion do we draw? What is the P-value for the problem above?
