Question 1 The average math SAT score is 511with a standard deviation of 119. A particular high school claims that its students have unusually high math SAT scores. A random sample of 50 students from this school was selected, and the mean math SAT score was 555. Is the high school justified in its claim? Explain. ▼ Pick one No Yes because the z-score (what is the z score) (?) is ▼ pick one not unusual unusual since it ▼...

(6) Solve the following probability by using the Central Limit Theorem: The mean undergraduate cost for tuition, fees room and board for four-year institutions was $26, 489 for a recent academic year. Suppose that the population standard deviation equals $3204 and that 36 four-year institutions are randomly selected. Finding the probability that the sample mean cost of these 36 schools is between $24000 and $26000: P(24000 <<26000) (a) Give a rough graph, and shade the desired area, (6b) value to...
