Total number of seniors = 500
2/5 the of 40 % of 500 went to the local university
40% of 500 = 200
Now, 2/5 th of 200
= 2/5 × 200 = 80
80 seniors from this high school are actually attending the local university.

13. 10 pts. The following are the math SAT scores of 15 high school seniors from three different high schools. Apply the Kruskal-Wallis test to determine whether there is a difference in SAT scores between the three high schools using a 0.05: . School 1: 498, 582, 527, 480, 549 . School 2: 435, 360, 372, 413, 512 . School 3: 608, 515, 661, 637, 554

(4)Five hundred students from a local high school took a college entrance examination. Historical data from the school record show that the standard deviation of test scores is 40. A random sample of thirty- six students is taken from the entire population of 500 students. The mean test score for the sample is three hundred eighty. Find (a) 95% confidence interval for the unknown population mean test score. (b) 95% confidence interval for the unknown population mean test score if...
A small liberal arts college receives applications for admission from 1000 high school seniors. The college has dormitory space for a freshman class of 100 students and will have to arrange for off-campus housing for any additional freshman. In previous years, an average of 60 percent of students that the college has accepted have elected to attend another school. Clearly the college should accept more than 100 students, but its administration does not want to take too big a chance...
Problem 10 (10 points). High school A and B play a series of local basketball championship games until one of them wins three games. Suppose that the games are independent and the probability that High school A wins a game is 0.60. (1) Find the probability that the series ends in live games. (2) If the series ends in five games, what is the probability that School A wins?
