Two independent samples have been selected, 91 observations from population 1 and 57 observations from population 2. The sample means have been calculated to be ₁ = 8.8 and ₂ = 13.4. From previous experience with these populations, it isknown that the variances are o = 28 and o2 = 34.(a) Determine the rejection region for the test ofusing a = 0.02.(b) Compute the test statistic.The final conclusion isO A. We can reject Ho-OB. There is not sufficient evidence to reject Ho.(c) Construct a 98 % confidence interval for (₁-₂).< (μ1 −μ₂) <Ho (1H₂) = 2.84H₁ (₁₂) > 2.84

A movie studio wishes to determine the relationship between the revenue from the rental of comedies on DVD and videotape and the revenue generated from the theatrical release of such movies. The studio has bivariate data from a sample of 13 comedies released over the past five years. These data give the revenue x from theatrical release (in millions of dollars) and the revenue y from DVD and videotape rentals (in millions of dollars) for each of the 13 movies. The least- squares regression equation computed from the data is y= 3.57+0.13x. The studio has plans for the DVD/video release of a comedy that grossed about 40.5 million dollars in theaters. The studio has predicted the rental revenue from this release using the regression equation and is now interested in both a prediction interval for this rental revenue and a confidence interval for the mean rental revenue of movies generating this same theater revenue. The studio has already computed the following for their data: • mean…
We are wondering if the proportions of voters who rejected the proposal to institute astate lottery vary by sex. Random samples from each sex are gathered and the following samplestatistics computed. For males (sample1): •proportion (p1) =0.35 •Sample size (n1) =178 For females (sample2): •Proportion (p2) =0.25 •Sample size (n2) =212 Test the research question atα=0.05 (two-tailed) with the five-step processes and concludeyour decisions. 1. Evaluate assumptions if we can use at-test and summarize parameters and statistics. 2. State the null hypothesis (i.e.,H0) and the working hypothesis (i.e.,H1). 3. Establish the critical region fort-distributions atα=0.05with a two-tailed test. 4. Compute the test statistics (i.e.,tobtained) and the corresponding probability (i.e.,p-value). 5. Make a decision and interpret test results.

Q1:Let p equal the proportion of drivers who use a seat belt in a country that does not have a mandatory seat belt law. It was claimed that p = 0.14. An advertising campaign was conducted to increase this proportion. Two months after the campaign, y = 104 out of a random sample ofn = 590 drivers were wearing their seat belts. The null and alternative hypotheses are given by
In a lake pollution study, the concentration of lead in the upper sedimentary layer of a lake bottom is measured from 25 sediment samples. The sample mean and the standard deviation of the measurements are found to be 0.38 and 0.06, respectively. Suppose Ho : u = 0.34 H1: u# 0.34 (a) State Type I and Type Il errors. (b) Conduct a hypothesis test at 0.01 level of significance by doing the seven-step classical approach. (please show all seven steps, formulas, calculations and the curve)

60% of students entering four-year colleges receive a degree within six years. Is this percent larger than for students who play intramural sports? 172 of the 249 students who played intramural sports received a degree within six years. What can be concluded at the level of significance of αα = 0.10? For this study, we should use (t-test, z-test) The null and alternative hypotheses would be: Ho: (symbol) (symbol) _____ (please enter a decimal) H1: (symbol) (symbol) _____ (Please enter a decimal) The test statistic (symbol) = _____ (please show your answer to 3 decimal places.) The p-value = _______ (Please show your answer to 4 decimal places.) The p-value is (symbol) αα Based on this, we should the null hypothesis. Thus, the final conclusion is that ... The data suggest the population proportion is not significantly larger than 60% at αα = 0.10, so there is sufficient evidence to conclude that the population proportion of students who…
