Consider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 5938 patients treated with this drug, 150 developed the adversereaction of nausea. Use a 0.01 significance level to test the claim that 3% of users develop nausea. Does nausea appear to be a problematic adverse reaction?.…….Identify the null and alternative hypotheses for this test. Choose the correct answer below.OA. Ho: p=0.03H₁: p<0.03orrOB. Ho: p=0.03H₁: p=0.03O C. Ho: p=0.03H₁: p>0.03OD. Ho: p=0.03H₁: p=0.03

Historically, the percentage of U.S. residents who support stricter gun control laws has been 55%. A recent Gallup Poll of 2500 people showed 1723 in favor of stricter gun control laws . Assume the poll was given to a random sample of people. QUESTION Test the claim that the proportion of those favoring stricter gun control has changed from 0.55. Perform a hypothesis test, using a significance level of 0.01. What are the hypotheses? Null: p=0.55 Alternate: p=0.55 Null: p=0.55 Alternate: p0.55 Null: p=0.55 Alternate: p ≠ 0.55

According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 2007 were for identity theft. In that year, Alaska had 321 complaints of identity theft out of 1,432 consumer complaints ("Consumer fraud and," 2008). Does this data provide enough evidence to show that Alaska had a lower proportion of identity theft than 23%? Test at the 5% level. viii) Comparing p-value and α value, which is the correct decision to make for this hypothesis test? A. Reject H B. Fail to reject Ho C. Accept Ho D. Accept HA Enter letter corresponding to correct answer. (ix) Select the statement that most correctly interprets the result of this test: A. The result is statistically significant at .05 level of significance. Evidence supports the claim that the proportion of complaints due to identity theft in Alaska is less than 23%. B. The result is statistically significant at .05 level of significance. There is not…

To compare the wearing of two types of automobile engines, 1 and 2, an experimenter chose to "pair" the measurements, comparing the wear for the two types of engines on each of 7 automobiles, as shown below. Determine whether these data are sufficient to infer at the 10% significance level that the two types of engines wear differently. The null and alternative hypotheses are:
Given the situation below, create a problem and determine (a) the null and alternative hypotheses, (b) test statistic, (c) rejection region, and (d) applicability of the CLT.
In performing a hypothesis T-test, the p-value was 0.00046 and the significance level was 5%. What is the conclusion? Is it a,b,or c? a. Reject the null hypothesis and accept the alternate hypothesis b. Accept both the null hypothesis and alternate hypothesis c. Fail to reject the null hypothesis
(c) Rashid carried out pyrolysis of sawdust in a semi-batch reactor and obtained replicates of measurement under the same conditions in order to test the precision of the method. The recorded values for biochar are 22.23, 22.18, 22.25, 22.09, and 22.17 wt%. Using a suitable test, analyze whether the value of 22.09 wt% is a valid measurement at a 95% confidence level?
