A statistics tutor wishes to study the effect that his tutoring has on his students. He randomly selects 4 newstudents and records their current grades in their statistics courses. After half a semester of tutoring, thestudents' grades are recorded again. The statistics tutor then uses a paired, two-sample hypothesis test todetermine if the differences between the before and after grades are statistically significant. (The tutorassumes a 5% level of significance.)Students:AВC DBefore83789387After80809686 d. Calculate the p-value from this hypothesis test.p =e. Which of the following is an appropriate conclusion?Given that p < a at a 5% level of significance, from the sample data, there is sufficient evidenceto conclude that the tutor is, in fact, effective.Given that p > a at a 5% level of significance, from the sample data, there is sufficient evidenceto conclude that the tutor is, in fact, effective.Given that p > a at a 5% level of significance, from the sample data, there is not sufficientevidence to conclude that the tutor is, in fact, effective.Given that p < a at a 5% level of significance, from the sample data, there is not sufficientevidence to conclude that the tutor is, in fact, effective.

Español A nationwide job recruiting firm wants to compare the annual incomes for childcare workers in Illinois and Massachusetts. Due to recent trends in the childcare industry, the firm suspects that the that the mean annual income of childcare workers in the state of Illinois is greater than the mean annual income of childcare workers in Massachusetts. To see if this is true, the firm selected a random sample of 15 childcare workers from Illinois and an independent random sample of 15 childcare workers from Massachusetts and asked them to report their mean annual income. The data obtained were as follows. 圖 Annual income in dollars an Illinois 45985, 37240, 46895, 45091, 41853, 45138, 53463, 51655, 47796, 51058, 40233, 49095, 40394, 39905, 49575 Massachusetts 38439, 42441, 43968, 53645, 41006, 46629, 49825, 47119, 37071, 37348, 40204, 49762, 39894, 47038, 41879 Send data to calculator The population standard deviations for the annual incomes of childcare workers in Illinois and in…
Jocelyn believes that the amount of sleep she tends to get on weekends differs from the amount of sleep she tends to get during the school week. To investigate this claim, she randomly selects 10 weekend days and 10 school days. She consults her smart watch to determine the number of hours she slept for each of the selected days. Here are the data. School week: 7, 7.5, 8, 6.5, 8, 7.5, 7, 6.5, 7, 8Weekend: 9.5, 9.5, 8.25, 8.5, 7.5, 10.25, 8, 7, 9.5, 10 Jocelyn would like to determine if these data provide convincing evidence that the true mean amount of sleep she gets on the weekend differs from the true mean amount of sleep she gets during the school week. She tests H0: μS – μW = 0, Ha: μS – μW ≠ 0, where μW = the true mean amount of sleep Jocelyn gets on the weekend and μS = the true mean amount of sleep she gets during the school week. The conditions for inference are met. What are the values of the test statistic and P-value for a t-test about a difference in means? Find the…

Indicate the statistical test you would conduct. Respondents in a survey of 1,000 households were asked about their travel history. Specifically, they were asked how often they have been to Europe in the past five years (using a ratio scale). People were also classified by interest type (art-lovers, food-lovers, or sports-lovers). The question is whether interest type influences travel history. Two-sample t-test Paired sample t-test One-way ANOVA none of those QUESTION 6 What is the corresponing alternative hypothesis for the scenario in question #5? The three interest types do not differ with regard to the number of times they have been to Europe in the last five years. Interest type and travel to Europe are not related. The number of times people have been to Europe does not depend on interest type. The three interest types differ with regard to the number of times they have been to Europe in the last five years.
