Homework Answers
please rate my answer
Number of ways in which 4 students can be selected from 19 = 19C4
= 19!/(4! x 15!)
= 3876
P(the four youngest students are selected) = 1/3876
= 0.000258

(04.05) Exactly 20% of the students in a school wear glasses. Sixty-five students are selected randomly to determine the probability that exactly 10 students wear glasses. Should a binomial probability density function or a cumulative distribution function be used? Explain. (4 points) a A binomial cumulative distribution function should be used because the question asks for determining the probability that exactly 10 students wear glasses. b A binomial probability density function should be used because the question asks for determining...

The mean score on a science assessment test for 49 randomly selected male high school students was 153. Assume the population standard deviation is 36. The mean score on the same test for 50 randomly selected female high school students was 147. Assume the population standard deviation is 34. At a= 0.05, can you support the claim that the mean score on the science assessment test for male high school students is greater than the mean score for female high...

Students at a local middle school were randomly selected to participate in a reading comprehension program. The program is designed to increase their reading comprehension. A total of 21 students each took a pretest before the program and posttest after the program. The mean differences in the posttest and pretest is 24. The administration decided that all students in the school would participate in the program next school year. Let µA denote the mean score of the posttest and µB...
