A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 201 vinyl gloves, 55% leaked viruses. Among 201 latex gloves, 13% leaked viruses. Using the accompanying display of the technology results, and using a 0.10 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1. Click the icon to view the technology results. What are the null and alternative hypotheses? O A. Ho: P1 P2 H1: P1 = P2 O B. Ho: P1 = P2 H: P, P2 O D. Ho: P1 > P2 H: P1 = P2 O E. Ho: P1

In a survey, 716 out of 1132 randomly selected adults in the United States said that they use cell phones while driving. a) Use a 0.02 significance level when testing the claim that the proportion of adults who use cell phones while driving is different than 70%. b) What does the conclusion mean?
In 2013, Steve LeCompte, a stock market trader and analyst, did a study to see which TV personalities made the best predictions for future stock values. One person he looked at was Jim Cramer who is the host of Mad Money on CNBC. The study monitored Jim Cramer's 678 of Jim Cramer's stock predictions, such as if the value of a stock would increase or decrease, and found that 320 of his predictions were correct. Use a significance level of 0.05 and the P-value approach to test the claim: Jim Cramer is correct less than half the time. d) State the decision e) State the conclusion
A hospital found out that there is a higher incidence of food poisoning in adults than in children. Thirty-four of the 250 adults and 16 of 275 children were food poisoned according to the hospital survey. Determine if there is enough evidence to believe the hospital claim. Use a 2.5% significance level.
A study was designed to compare the smoking habits of married men with those married women. A random sample of 240 men revealed that 180 smoked. A random sample of 220 women indicate that 54 smoked. At the 0.01 significance level does the evidence show that a higher proportion of men smoke?
A drug company is interested in investigating whether the color of their packaging has any impact on sales. To test this, they used five different colors (blue, green, orange, red, and yellow) for their packages of an over-the-counter pain reliever, instead of the traditional white package. The following table shows the number of packages of each color sold during the first month. Package color Blue Green Orange Red Yellow Number of packages sold 310 292 280 216 296 Using a 1% significance level, test the null hypothesis that the number of packages sold of each of these five colors is the same. Make sure to state the null and alternative hypotheses.
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?
