**Transcription for Educational Website**Seventeen individuals are scheduled to take a driving test at a particular DMV office on a certain day, nine of whom will be taking the test for the first time. Suppose that six of these individuals are randomly assigned to a particular examiner, and let X be the number among the six who are taking the test for the first time.**(a)** What kind of distribution does X have (name and values of all parameters)?- ○ b(x; 6, 9/17)- ○ nb(x; 6, 9/17)- ○ h(x; 6, 17)- ● h(x; 6, 9, 17)- ○ nb(x; 6, 9, 17)- ○ b(x; 6, 9, 17)The correct answer is: **h(x; 6, 9, 17)** (with a checkmark indicating selection)**(b)** Compute P(X = 2), P(X ≤ 2), and P(X > 2). (Round your answers to four decimal places.)- P(X = 2) = [ ] ✘- P(X ≤ 2) = [ ] ✘- P(X > 2) = [ ] ✘**(c)** Calculate the mean value and standard deviation of X. (Round your answers to three decimal places.)- Mean = [ ] individuals- Standard deviation = [ ] individualsNote: The area where numerical answers should be entered is blank with an “Enter a number” prompt.

You receive a brochure from a large university. The brochure indicates that the mean class size for full-time faculty is fewer than 32 students. You want to test this claim. You randomly select 18 classes taught by full-time faculty and determine the class size of each. The results are shown in the table below. At a= 0.10, can you support the university's claim? Complete parts (a) through (d) below. Assume the population is normally distributed. 32 31 26 31 34 41 25 24 290 27 30 33 30 29 28 30 25 23 OD.

Aspirin III: Decision and Conclusion Regarding the experiment in the data frame Aspirin from the abd package, the researchers wanted to know whether or not taking aspirin affects one's risk of developing cancer. Recall that they defined their parameters as follows: p1 = the proportion of ALL individuals who would develop cancer, if all of them were to take aspirin like the subjects in the Aspirin group did. p2 = the proportion of ALL individuals who would develop cancer, if all of them were to take a placebo, like the subjects in the placebo group did. They ran the code for a two-sided significance test and got the following results: ## ## ## Inferential Procedures for the Difference of Two Proportions p1-p2:## cancer grouped by treatment ## ## ## Descriptive Results:## ## yes n estimated.prop## Aspirin 1438 19934 0.07214## Placebo 1427 19942 0.07156## ## ## Inferential Results:## ## Estimate of p1-p2: 0.0005805 ## SE(p1.hat - p2.hat): 0.002586 ## ##…

Q. 1In the population, the average score on a test of self-esteem is 50 (σ= 5). You select a randomsample of 25 students who score a mean of 53.a. Shine claims that these students don’t have very high self-esteem, because they are only 3points above the population mean. Why can’t she make this claim merely by looking atthe X? .b. What should she do? .c. What is the z-score for this sample? .d. What conclusion do you draw about your sample? .
