A test was given to a statistics class. Results for each gender and for one student in each gender are given. From the information provided, determine which student received a relatively higher grade. The female scored a 80 with μ = 84 and σ = 2. The male scored a 76 with μ = 80 and σ = 2. The male student has a higher relative grade than the female student Both students have the same relative grade The female student has a higher relative grade than the male student O Not enough information to determine
Don't answer if you already answered this. If i see the same solutions, i'll downvote you. Follow the instructions. Typewritten for upvote. No upvote for handwritten. Thank you
Complete the correct calculator with the values from the problem. 6.) Compare the p-value with the level of significance. Is the p-value less than or greater than alpha? 7.) Based on your answer in #6, do we reject or fail to reject the null Ho? 8.) Based on your answer in #7, do we reject or fail to reject the claim? 9.) At the 0.01 level of significance, is there enough evidence to REJECT the principal’s claim? Give a full conclusion statement. Don't forget to include the level of significance and restate the claim.
Sir pls stepwise and i only need e) part. Pls correct with explanation.
The graph portrays the decision criterion for a hypothesis test for a population mean. The null hypothesis is H:u=µ. The curve is the normal curve for the test statistic under the assumption that the null hypothesis is true. Use the graph to solve the problem. A graphical display of the decision criterion follows. do 0.9 Do not reject H Reject H, 0.8- 0.7- 0.6- 05- 04 0.3- 0.2- 0.1- !0.014 -059 0.59 L18 137 236 295 3.54 2.197 Determine the rejection region.

Use the six steps of hypothesis testing to answer the following question. Remember to determine if the problem is a Z test or T test as that will influence your critical value. You believe you have discovered a topical solution that heals wounds faster. The average number of days it takes to remove stiches after surgery in all hospital patients is 12. In a sample of 29 patients the average number of days to remove stiches is 10.5 with a std dev. Of 1.2 Did your solution lessen the number of days patients had stiches
Solve the problem. A researcher conducts a hypothesis test on a population proportion. Her null and alternative hypothesis are Ho: p = 0.6 and Ha: P < 0.6. The test statistic and p-value for the test are z = -1.51 and p-value = 0.0655. For a significance level of a = 0.05, choose the correct conclusion regarding the null hypothesis. O None of these. O There is sufficient evidence to warrant rejection of the null hypothesis. There is insufficient evidence to warrant rejection of the null hypothesis.
