Þorgerður, a scientist, used a paired t-test to examine the effectiveness of a drug she is developing. She obtained a p-value =% 3D 0.005 and concluded that the drug was effective (she used a = 0.05). Suppose the drug does not actually work. Which of the following statements is correct? 1. Þorgerður should not reject the null hypothesis because the p-value is too large. 2. Type I error occurred. 3. An error of type II occurred. 4. There was no error
Q1. Does this statement accurately represent Type I error? Rejecting the Ho after a test statistic results in a p-value of .085 at α=0.05.A. YesB. NoC. None of the above
Molly works for a meat producer, and she needs to determine whether containers of ground beef have the correct fat content. She obtains a random sample of 120 containers of ground beef and finds that 84 percent have the correct fat content. Molly then conducts a hypothesis test of H0:p=0.80H0:p=0.80 versus Ha:p≠0.80Ha:p≠0.80 and calculates a test statistic of 1.10 with a pp-value of 0.273. Which of the following best represents the meaning of the pp-value? If the population proportion is 0.84, the probability of observing a sample proportion of 0.80 is 0.273. A If the population proportion is 0.84, the probability of observing a sample proportion of at least 0.04 less than 0.84 is 0.273. B If the population proportion is 0.80, the probability of observing a sample proportion within 0.04 of 0.80 is 0.273. C If the population proportion is 0.80, the probability of observing a sample proportion at least 0.04 greater than 0.80 is 0.273. D If the…

Suppose the coffee industry claimed that the average adult drinks 1.7 cups of coffee per day. To test this claim, a random sample of 50 adults was selected, and their average coffee consumption was found to be 1.85 cups of daily coffee consumption per day is 0.5 cups. Using a = 0.10, complete parts a and b below. a. Is the coffee industry's claim supported by this sample? Determine the null and alternative hypotheses.
