In the population of senior students at Shermer High School, the proportion who plan to attend college is 0.64. In a random sample of 100 students from this population, the proportion who plan to attend college is 0.75. We would call the value 0.64 a P-value. z-score. parameter statistic significance level.
Floretta, a golfer, claims that her drive distance is not equal to 238 meters, on average. Several of her friends do not believe her, so she decides to do a hypothesis test, at a 5% significance level, to persuade them. She hits 19 drives, collects the proper data, and works through the testing procedure: • Hou = 238; HH #238 • a = 0.05 (significance level) The test statistic is X-Ho Zo == 256-238 14 V19 <= 5.6 • The critical values are -20.025 = -1.96 and 20.025 = 1.96. Conclude whether to reject or not reject Ho. and interpret the results. Select the correct answer below: Reject Ho. At the 5% significance level, the test results are not statistically significant and at best, provide weak evidence against the null hypothesis. Reject Ho. At the 5% significance level, the data provide sufficient evidence to conclude that the mean distance is not equal to 238 meters. Do not reject Ho. At the 5% significance level, the test results are not statistically significant and at best, provide…
Under what circumstances is a t statistic used instead of a z-score for a hypothesis test? Justin wants to know whether a commonly prescribed drug does improve the attention span of students with attention deficit disorder (ADD). He knows that the mean attention span for students with ADD who are not taking the drug is 2.3 minutes long. His sample of 12 students taking the drug yielded a mean of 4.6 minutes. Justin can find no information regarding σx , so he calculated s2x =1.96. Identify the independent and dependent variables. In a sentence, state the null hypothesis being tested. c. Using symbols, state the null and alternative hypotheses
Perform the following hypothesis test: HO: µ = 10 H1: µ 10 The sample mean is 9.55, population standard deviation of 1.5 and a sample size of 51. Use a 5% significance level. What is the value of the test statistic? (Give your answer rounded to 2 decimals) (Be careful to make sure your + or - sign is correct)What is the p-value for this problem?
Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x = 98.46, y = 99.4, r=0.883, P-value = 0.000, and y=-14.65 +1.16x, where x represents the IQ score of the wife. Find the best predicted value of y given that the wife has an IQ of 101? Use a significance level of 0.05. Click the icon to view the critical values of the Pearson correlation coefficient r. The best predicted value of y is (Round to two decimal places as needed.)
