2. Michael suspects that the quarter in his pocket may not be a fair coin. He flips it 50 times, and toconduct a two-sided hypothesis test at the a = 0.05 significance level. Heads appears h = 35 times.(a) Does Michael reject Ho?(b) For what values of h would Michael reject Ho, while fixing n = 50?

The question is about hypothesis testing.Given :No. of times a coin is flipped ( n ) = 50No. of…

In a recent Super Bowl, a TV network predicted that 40 % of the audience would express an interest in seeing one of its forthcoming television shows. The network ran commercials for these shows during the Super Bowl. The day after the Super Bowl, and Advertising Group sampled 119 people who saw the commercials and found that 42 of them said they would watch one of the television shows.

60% of students entering four-year colleges receive a degree within six years. Is this percent smaller than for students who play intramural sports? 130 of the 241 students who played intramural sports received a degree within six years. What can be concluded at the level of significance of a = 0.01? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho:1?v Но: 7Select an answer v (please enter a decimal) H1:1?v|Select an answer v (Please enter a decimal) c. The test statistic ? (please show your answer to 3 decimal places.) d. The p-value (Please show your answer to 4 decimal places.) e. The p-value is ? va f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusiion is that .. The data suggest the population proportion is not significantly smaller than 60% at a = 0.01, so there is not sufficient evidence to conclude that the population proportion of students who played intramural sports who received…
What number goes in the Null Hypothesis for the following? Fred and Jack have been gambling with a die and Jack is losing. Thus, Jack accuses Fred of having an unfair diethat doesn’t land on Box Cars (six’s) as often as it should. To decide, Jack rolls the die 30 times and it lands on Box Cars only 12% of the time.

(b) The state of Wisconsin would like to understand the fraction of its adult residents that consumed alcohol in the last year, specifically if the rate is different from the national rate of 70%. To help them answer this question, they conduct a random sample of 852 residents and ask them about their alcohol consumption. In symbols, the hypotheses are: Ho: p = 596 Ha: p > 596 Но: р %3 0.70 На: р > 0.7 Ho: p = 596 На: # 596 Ho: p = 0.70 Ha: p z 0.70
3. A sample of n=25 individuals is selected from a population with μ=80, and a treatment is administered to the sample. What is expected if the treatment has no effect? a.The sample mean after the treatment should be very different from 80 and should lead you to reject the null hypothesis. b. The sample mean after the treatment should be very different from 80 and should lead you to fail to reject the null hypothesis. c.The sample mean after the treatment should be close to 80 and should lead you to reject the null hypothesis. d.The sample mean after the treatment should be close to 80 and should lead you to fail to reject the null hypothesis.
7. The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) α = 0.01, (b) x = 0.05, and (c) α = 0.10. P = 0.1176 (a) Do you reject or fail to reject Hå at the 0.01 level of significance? O A. Fail to reject Ho because the P-value, 0.1176, is greater than α = 0.01. Reject Hå because the P-value, 0.1176, is greater than α = 0.01. O B. O C. Fail to reject Ho because the P-value, 0.1176, is less than α = 0.01. O D. Reject Ho because the P-value, 0.1176, is less than α = = 0.01. (b) Do you reject or fail to reject Ho at the 0.05 level of significance? O A. Fail to reject Ho because the P-value, 0.1176, is less than α = 0.05. B. Fail to reject Ho because the P-value, 0.1176, is greater than α = 0.05. O C.
