Sample Exam Solutions Problem 1 (Hypothesis testing) A company that manufactures travel goods is particularly concerned that the mean weight of the roll-on cabin bags should not exceed 3 kg as many airlines limit the weight of carry-on luggage on their planes to 7 kg. Past experience allows the assumption that the std. dev = 0.03 kg. A sample of 50 cabin bags is selected and the sample mean is 3.009 kg. Using a 0.05 significance‚ conduct a hypothesis test to determine if the population mean weight

MAT 300 M&Ms® Project Part 5 (3 pts) Using the methods in Section 8.4‚ test the hypothesis (α = 0.05) that the population proportions of red and brown are equal (pred = pbrown). You are testing if their proportions are equal to one another‚ NOT if they are equal to one another AND equal to 13%. NOTE: These are NOT independent samples‚ but we will use this approach anyway to practice the method. This also means that n1 and n2 will both be the total number of candies in all the bags. The

Question 3 Marks: 1 A random sample of size 15 is selected from a normal population. The population standard deviation is unknown. Assume that a two-tailed test at the 0.10 significance level is to be used. For what value of t will the null hypothesis not be rejected? Choose one answer. |[pic]|a. To the left of -1.345 or to the right of 1.345 [pic] | | |[pic]|b. To the left of -1.645 or to the right of 1.645 [pic] | |

Through this project I want to prove that the prediction of the Bureau of Labor in the United States is true‚ and reject the hypothesis that the growth of this industry is less than 5%. 2. Body: You can add a theoretical discussion in your project…this is optional. But‚ if you want to discuss your study’s goal and basic theoretical truth behind your hypotheses‚ you are welcome

The first step is to state the null hypothesis and an alternative hypothesis. * Null hypothesis: The proportion of rookies‚ veterans‚ and All-Stars is 30%‚ 60% and 10%‚ respectively. * Alternative hypothesis: At least one of the proportions in the null hypothesis is false. * Formulate an analysis plan. For this analysis‚ the significance level is 0.05. Using sample data‚ we will conduct a chi-square goodness of fit test of the null hypothesis. * Analyze sample data. Applying
