You are concerned that nausea may be a side effect of Tamiflu, but you cannot just give Tamiflu to patients with the flu and say that nausea is a side effect if people become nauseous. However, past research indicates that about 30% of people who get the flu experience nausea, and you believe that the percentage of those who experience nausea while having the flu and taking Tamiflu will be greater than 30%, which would indicate that nausea is a side effect of Tamiflu.
a) If you going to test this claim at the 0.05 significance level, what would be your null and alternative hypotheses?

H1: ____ _____

- In January 2007 Consumer, Reports published a study of bacterial contamination of chicken sold in the United States. They purchased 525 broiler chickens from various stores in 23 states and tested them for bacterial contamination. Lab tests indicated 83% of the chickens were contaminated with Campylobacter. How would you justify a claim by the USDA that the number of chickens tested was not large enough since 9 billion chickens are sold each year in the U.S.? What is the impact on the confidence interval estimate if a larger sample is used?arrow_forwardYou are concerned that nausea may be a side effect of Tamiflu, but you cannot just give Tamiflu to patients with the flu and say that nausea is a side effect if people become nauseous.

- About 42.3% of Californians and 19.6% of all Americans over age five speak a language other than English at home. A recent survey of 962 North Carolinians indicated that 17.4% of those sampled speak a language other than English at home. Test the claim that the percentage of North Carolinians that speak a language other than English at home is significantly different from the rate of all Americans that speak a language other than English at home.

- The cost of attending your college has once again gone up. Although you have been told that education is investment in human capital, which carries a return of roughly 10% a year, you (and your parents) are not pleased. One of the administrators at your university/college does not make the situation better by telling you that you pay more because the reputation of your institution is better than that of others. To investigate this hypothesis, you collect data randomly for 100 national universities and liberal arts colleges from the 2000-2001 U.S. News and World Report annual rankings.Next you perform the following regression cost^= = 7,311.17 + 3,985.20 × Reputation – 0.20 × Size (2,058.63) (664.58) (0.13) + 8,406.79 × Dpriv – 416.38 × Dlibart – 2,376.51 × Dreligion(2,154.85) (1,121.92) (1,007.86) R2=0.72, SER=3,773.35 where Cost is Tuition, Fees, Room and Board in dollars, Reputation is the index used in U.S. News and World…arrow_forwardThe cost of attending your college has once again gone up.

Put another way, there is an almost 70 percent probability in that case that the test will falsely indicate a person has antibodies. The reason for this is a simple matter of statistics. The lower prevalence there is of a trait in a studied population —here, coronavirus infection — the more likely that a test will return a false positive. While a more accurate test will help, it can’t change the statistical reality when the base rate of infection is very low.” Suppose we select one person at random from a population in which 5 percent of people are infected with COVID-19, and give that…arrow_forward
