This is because nausea is common for people who have the flu. From past studies you know that about 33% of people who get the flu experience nausea. You collected data on 2371 patients who were taking Tamiflu to relieve symtoms of the flu, and found that 841 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 greater than 33%. *.** ▸ Ezra Mill X HH Chief Be X V H₁: ?

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

A medical journal published new medical research about diastolic blood pressure. Let the mean diastolic blood pressure reading be u mmHg. If a doctor wants to know if the new medical research discussed in the journal results in diastolic blood pressure readings that are, on average, less than 75 mmHg, what are the null and alternative hypotheses? Select the correct answer below: Ho: µ = 75; Ha:H 75 %3D O Ho: µ = 75; Ha: µ + 75
Recall the scenario from the previous page. A psychic claims to be able to predict the outcome of coin flips before they happen. Someone who guesses randomly will predict about half of coin flips correctly. In 100 flips, the psychic correctly predicts 57 flips. Do the results of this test indicate that the psychic does better than random guessing? The hypotheses are H0: p=0.50p=0.50 Ha: p>0.50p>0.50 where p is the proportion of correct coin flip predictions by the psychic. 1. determine the P-value. 2. Give the conclusion based on the P-value above. Use a 5% level of significance.
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.

According to a report on consumer fraud and identity theft, 21% of all complaints for a year were for identity theft. In that year, Ohio had 273 complaints of identity theft out of 1405 consumer complaints. Does this data provide enough evidence to show that Ohio had a lower proportion of identity theft than 21%? Test at the 1% level. State the hypotheses. Ho: P = v or .21 Ha: p
