0 Question 15 v B 1/2 pts '0 3 Z 98 6) Details A psychologist is interested in constructing a 90% confidence interval for the proportion of people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain. Of those randomly selected, 62 of the 837 people agreed with this theory. a. With 90% confidence the proportion of all people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain is between:]and [:]. Round to 3 decimal places. b. If many groups of 837 randomly selected people are surveyed, then a different confidence interval would be produced from each group. About C] percent of these confidence intervals will contain the true population proportion of all people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain and about C] percent will not contain the true population proportion. 0 Question 1? v You are concerned that nausea may be a side effect of Tamiflu, but you cannot just give Tamiu to patients with the flu and say that nausea is a side effect if people become nauseous. This is because nausea is common for people who have the flu. From past studies you know that about 31% of people who get the flu experience nausea. You collected data on 2224 patients who were taking Tamiu to relieve symtoms of the uI and found that 256 experienced nausea. Use a 0.01 significance level to test the claim that the percentage of people who take Tamiflu for the relief of u symtoms and experience nausea is greater than 31%. a} Identify the null and altemative hypotheses? rim-C] H..-:] b) What type of hypothesis test should you conduct [left-, right-, or two-tailed}? O left-tailed O right-tai led O two-tailed c) Identify the appropriate significance level. C] d) Calculate your test statistic {use p rounded to 4 decimal places]. Round your test statistic to 4 decimal places. C] e) Calculate your p-value and round to 4 decimal places. 0 Do you reject the null hypothesis? 0 We reject the null hypothesis, since the p-value is less than the significance level. 0 We reject the null hypothesis, since the p-value is not less than the significance level. 0 We fail to reject the null hypothesis, since the p-value is less than the significance level. 0 We fail to reject the null hypothesis, since the p-value is not less than the significance level. g) Select the statement below that best represents the conclusion that can be made. 0 There is sufficient evidence to warrant rejection of the claim that the percentage of people who experience nausea is greater than 31%. Q There is not sufficient evidence to warrant rejection of the claim that the percentage of people who experience nausea is greater than 3196. O The sample data support the claim that the percentage of people who experience nausea is greater than 3196 Q There is not sufficient sample evidence to support the claim that the percentage of people who experience nausea is greater than 31% h) Can we conclude that nausea a side effect of Tamiflu? 0 Yes O No Question 18 v Score on last try: 1.5 of 2 pts.
