In order to be considered for admission to a famous computer school, candidates must score I. The top 14% on a logic test. This test has mean score of 250 and a standard deviation of 25. A) Assuming the scores are normally distributed, find the lowest possible score necessary to be in the top 14% in this test: B) Calculate m the Z-Value used in the calculation. C) Calculate the lowest possible score to be considered for admission.

Find the five-number summary for the following 10 values: 22, 22, 25, 19, 35, 29, 28, 19, 32, 27 Find- Q1 : Q3: I need to know how to do this by hand. I CANNOT USE EXCEL FOR MY EXAM. I know how to find the mean, min and max but do not get quartile 1 and quartile 3. Thank you!

Suppose that, at the end of last semester, Marie gave her introductory statistics class a final exam. After grading these exams, she created a histogram illustrating the distribution of exam scores for the 70 students in the class.   Each of the bars in this histogram includes only the left endpoint of the interval, except for the bar representing scores between 90 and 100 points, which also includes the right endpoint. What percentage of students scored between 60 and 80 points on the exam? Round your answer to the nearest tenth of a percent. Number of students who scored at least 80 points =   students Percentage of students who scored between 60 and 80 points =   %

On a multiple choice test with 10 questions, each question has four possible answers, one of which is correct. For students who guess at all answers, find the standard deviation for the number of correct answers.
