Many fast-food restaurants have soft drink dispensers with preset amounts, so that when the operator merely pushes a button for the desired rink the cup is automatically filled. This method apparently saves time and seems to increase worker productivity. A researcher randomly selects 9 workers from a restaurant with automatic dispensers and 9 works from a restaurant with manual dispensers. At a 1% significance level, use the Mann-Whitney U Test to test whether workers with automatic dispensers are significantly more productive. Automatic (Group 1): 153, 128, 143, 110, 152, 168, 144, 137, 118Manual (Group 2): 105, 118, 129, 114, 125, 117, 106, 92, 126 What rank will be given to the observation value, 118 that is in both the automatic and manual groups? (Round answer to 1 decimal). When rounding the U test statistic up to the next value, what is the p-value from the Mann Whitney Table of p-values? (Round to 4 decimal places)
A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 287 vinyl gloves, 69% leaked viruses. Among 287 latex gloves, 14% leaked viruses. Using the accompanying display of the technology results, and using a 0.01 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1.
A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 276 vinyl gloves, 63% leaked viruses. Among 276 latex gloves, 14% leaked viruses. Using the accompanying display of the technology results, and using a 0.05 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1.
A geneticist conducted a hybridization experiment with peas, which resulted in offspring consisting of 410 peas with green pods and 150 peas with yellow pods. According to Mendel’s theory, 1/4 of the offspring peas should have yellow pods. Use a 0.05 significance level to test the claim that the proportion of peas with yellow pods is equal to 0.25. Provide answers below.
Vinyl vs Latex ProblemResearchers conducted a study comparing the effectiveness of vinyl gloves and latex gloves. Among 229 vinyl gloves, 158 leaked viruses. Among 229 latex gloves, 133 leaked viruses. Use a 0.05 significance level to test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1. State the claim, null, and alternative hypothesis. Claim: p1 p2 HO: p1 p2 H1: p1 p2
An exercise science major is planning to investigate the hypothesis that diet plus exercise is more effective for weight loss than either diet or exercise alone. She will randomly assign participants to four different conditions based on diet (hi/lo cal) and high/low exercise level. Analysis: ? Ho: ?
A national publishing house claims that 35% of all weekly magazine readers inSouth Africa read their publication. Test this claim at the 5% significance level, if a survey found that 160 out of a random sample of 500 magazine readers said that they read the relevant publication.
In a clinical study of an allergy drug 98 of the 202 subjects reported experiencing significant relief from their symptoms. At the 0.01 significance level, test the claim that at least half of those using the drug experience relief.
A doctor is concerned that nausea may be a side effect of Tamiflu, but is not certain because nausea is common for people who have the flu. She researched some past studies, and found that about 25% of people who get the flu and do not use Tamilflu experience nausea. She then collected data on 2492 patients who were taking Tamiflu, and found that 589 experienced nausea. Use a 0.01 significance level to test the claim that the percentage of people who take Tamiflu for the relief of flu symtoms and experience nausea is 25%. What is the test statistic for the given statistics? What is the p-value for this test?
