- What are the Test Statistic and P-Value?Suppose 40 % of students who drive to campus carry jump cables in their cars in case of a dead battery emergency. Suppose further your car battery dies and that you do not have jumper cables in your car. Consider the experiment of stopping other students and asking to borrow jumper cables so that you are able to "jump" or re-energize your car battery. Accordingly, let X ="number of students who must be stopped before find a student with jumper cables." i) Give the probability mass function for this random variable, i.e. Px(X = x) ii) Compute the probability Px(X = 1). iii) Compute the probability Px(X 5). v) What is the expected value in this experiment? vi) What is the variance in this experiment?Percent of school children receiving free or reduced-fee lunches at school (X, P_RFM) and percent of bicycle riders wearing a helmet (Y, P_HELM) at 7 schools.

The article ["CSI Effect Has Juries Wanting More Evidence" (USA Today, 2004)](https://usatoday30.usatoday.com/news/nation/2004-08-05-csi-effect_x.htm) examines how the popularity of crime-scene investigation television shows in influencing jurors' expectation of what evidence should be produced at a trial. In a survey of 500 potential jurors, one study found that 350 were regular watchers of at least one crime-scene forensics television series. i) Assuming that it is reasonable to regard this sample of 500 potential jurors as representative of potential jurors in the US, use the given information to construct and interpret a 95\% confidence interval for the proportion of all potential jurors who regularly watch at least one crime-scene investigation series. ii) Using the same sample proportion as part (i), construct a 95\% confidence interval for same proportion but instead use a sample size of 50. iii)…I need assistance with qs 4,5,6,7,8What is a point of inflasionA ALEKS - Adissa Ou https://www-awu.aleks.com/alekscgi/x/Isl.exe/10_u-IgNslkr7j8P3jH-liJQhiJODya094wj2g W7.5: ALEKS Final Exam Question 10 of 25 (4 points) | Question Attempt: 1 of 1 = 1 = 2 = 3 = 4 = 5 = 6 A number cube with faces labeled from 1 to 6 will be rolled once.
