Module 6Hypothesis TestingNameCourse and YearExercise 6.1,1. Suppose you are testing Ho = .45 versus Ha >.45 random sample of 310 peopleproduces a value of p = .465. Use= .05 to test this hypothesis.2. Instructions: Five - step Hypothesis Testing Procedure Used:A criminologist was interested whether there was disparity in sentencing based onthe race of the defendant. She selected at random 18 burglary convictions andcompared the prison terms given to the 10 whites and 8 blacks sampled. Thesentenced length s (in years) are shown for the white and blacks offenders. Using thedata, test the null hypothesis that white and blacks convicted burglary in thisjurisdiction do not differ with respect prison sentence length.Black8735 43547 5 5 6 4 3 2454WhiteNote: Follow all the steps and use two decimal places, round off if possible.Analysis of Variance (ANOVA)Exercise 6.2.1.

The school registrar estimates that the dropout rate of senior high schools in Cavite is 47%. Last year, 187 freshmen from a random sample of 10 Cavite senior high school withdrew. At 5% significance level, is there enough evidence to reject the registrar's claim? Step 1: State the hypothesesStep 2: The level of significance, one/two-tailed test, degrees of freedom (if applicable)Step3: Statistical TestStep 4: ComputationStep 5: Decision RuleStep 6: Reject null hypothesis or failed to rejectStep 7: Conclusion
A certified public accountant claims that more than 30% of all accountants advertise. A sample of 400 accountants in Rizal province shows that 112 had used some form of advertising.

Suppose we are interested in the relationship between individuals’ place of residence (rural versus urban) and their political affiliation (Republican versus Democrat). A random sample of 100 individuals yields the following crosstabulation: Political Affiliation Place of Residence Republican Democrat Rural 21 29 Urban 14 36 a) In words, what is the null hypothesis to be tested? b) Is the relationship between place of residence and political affiliation statistically significant at the .05 level? (Be sure to show the statistics that lead to your decision.) c) Compute and interpret an appropriate measure of association for the relationship between these two variables.
Kenneth, a competitor in cup stacking, claims that his average stacking time is 8.2 seconds. During a practice session, Kenneth has a sample stacking time mean of 7.8 seconds based on 11 trials. At the 4% significance level, does the data provide sufficient evidence to conclude that Kenneth's mean stacking time is less than 8.2 seconds? Accept or reject the hypothesis given the sample data below. H0:μ=8.2 seconds; Ha:μ<8.2 seconds α=0.04 (significance level) z0=−1.75 p=0.0401 Select the correct answer below: a. Do not reject the null hypothesis because the p-value 0.0401 is greater than the significance level α=0.04. b. Reject the null hypothesis because the p-value 0.0401 is greater than the significance level α=0.04. c. Reject the null hypothesis because the value of z is negative. d. Reject the null hypothesis because |−1.75|>0.04. e. Do not reject the null hypothesis because |−1.75|>0.04.
A manager for an insurance company believes that customers have the following preferences for life insurance products: 20% prefer Whole Life, 10% prefer Universal Life, and 70% prefer Life Annuities. The results of a survey of 200 customers were tabulated. Is it possible to refute the sales manager's claimed proportions of customers who prefer each product using the data? Product Number Whole 78 Universal 34 Annuities 88 Step 1 of 10 : State the null and alternative hypothesis. Step 2 of 10: What does the null hypothesis indicate about the proportions of customers who prefer each insurance product? Step 3 of 10: State the null and alternative hypothesis in terms of ehe expected proportions for each category. Step 4 of 10: Find the expected value for the number of customers who prefer whole life. Round your answer to two decimal places. Step 5 of 10: Find the expected value for the number of customers who prefer universal life. Round your answer to two…
