The combined SAT scores for the students at a local high school are normally distributed with a mean of 1547 and a standard deviation of 291. The local college includes a minimum score of 820 in its admission requirements. What percentage of students from this school earn scores that satisfy the admission requirement? P(X > 820) = Enter your answer as a percent accurate to 1 decimal place (do not enter the "%" sign). Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.

a sample of n=300 male college freshmen has a mean weight of 160 with a standard devation of 11. how many of the 300 observed weights fall within (A)2 standard deviations of the mean? (B) 3 standard deviations of the mean? (C) 5/2 deviations of the mean? Show the interval in each case.
A basketball coach was trying a new training program with this year’s team. He was hoping to increase the average number of points scored per game and started collecting team data as the season began. His data of last year show the average number of points per game was 56, with a standard deviation of 7 points. After the first 9 games of the season, he found the average to be 60 points per game. What z-score can be derived from this research? What are the symbols that should be used to state a null hypothesis

Logan and Brian began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Logan took a test in Art History and earned a 76.8, and Brian took a test in English and earned a 68.9. Use the fact that all the students' test grades in the Art History class had a mean of 71.9 and a standard deviation of 11.6, and all the students' test grades in English had a mean of 61 and a standard deviation of 9.4 to answer the following questions.a) Calculate the z-score for Logan's test grade.z=z= [Round your answer to two decimal places.] b) Calculate the z-score for Brian's test grade.z=z= [Round your answer to two decimal places.]c) Which person did relatively better? Logan Brian They did equally well.

Suppose that the distribution of scores on an exam can be described by a normal curve with mean 110. The 16th percentile of this distribution is 80. (Use the Empirical Rule.) (a) What is the 84th percentile? (b) What is the approximate value of the standard deviation of exam scores? (c) What z score is associated with an exam score of 125? (d) What percentile corresponds to an exam score of 170? (e) Do you think there were many scores below 20? Explain. A score of 20 is? standard deviations below the mean, and so the percentage of scores below 20 would be approximately ... how many percentage
