9. An engineering school reports that 56% of its students were male (M), 35% of its students were between the ages of 18 and 20 (A), and that 25% were both male and between the ages of 18 and 20.What is the probability of choosing a random student who is a female or between the ages of 18 and 20? Assume P(F) = P(not M). Your answer should be given to two decimal places.

10. An engineering school reports that 55% of its students were male (M), 30% of its students were between the ages of 18 and 20 (A), and that 24% were both male and between the ages of 18 and 20.What is the probability of a random student being male or between the ages of 18 and 20? Your answer should be rounded to two decimal places.

11. Let A and B be two independent events such that P(A) = 0.37 and P(B) = 0.53.
What is P(A or B)? Your answer should be given to 4 decimal places.

12. Let A and B be two independent events such that P(A) = 0.1 and P(B) = 0.8.
What is P(A and B)? Your answer should be given to 2 decimal places.

13. Let A and B be two disjoint events such that P(A) = 0.25 and P(B) = 0.03.
What is P(A and B)?

14. Let A and B be two disjoint events such that P(A) = 0.27 and P(B) = 0.52.
What is P(A or B)?

An engineering school reports that 55% of its students are male (M), 37% of its students are between the ages of 18 and 20 (A), and that 30% are both male and between the ages of 18 and 20. What is the probability of a random student being chosen who is a female and is not between the ages of 18 and 20? Your answer should be to two decimal places. An engineering school reports that 50% of its students...

56 randomly selected male students at a commuter college were asked if they lived with their parents. 24 responded yes. 51 randomly selected female students at the same college were asked if they lived with their parents. 21 responded yes. The Dean of Students believes that more male students than female students live independently of their parents. Test the dean’s assumption. Use α=.05 1. Pooled sample proportion & compute the test statistic (Population 1 is Males, Population 2 is females)...

In a secondary school, there are 400 male students and 600 female students. 50% of the male students and 55% of the female students are in senior secondary curriculum, the others are in junior secondary curriculum. The school had appointed 8% of senior male students and 10% of senior female students to be the student leaders. No junior secondary student can be student leader. (a) If a student is selected at random in the school, find the probability that (i)...

1. A researcher team reports that the elementary school students who were served orange juice during the science test had higher scores than the students who did not given orange juice. For this study, what is the independent variable? A. the students who were not served orange juice. B. the performance on the science test. C. the students who were served orange juice. D. whether or not orange juice was served. 2. A researcher team reports that the elementary school...

Traditionally 35% of the students at Wortham University were in the Business College, 35% of the students were in the Liberal Arts College, and 30% of the students were in the Education College. To see whether or not the proportions have changed, a sample of 300 students was taken. Ninety of the sample students are in the Business College, 120 are in the Liberal Arts College, and 90 are in the Education College. The hypothesis is to be tested at...

56 randomly selected male students where asked if they lived with their parents. 24 responded yes. 51 randomly selected female students were asked if they lived with their parents. 21 responded yes. Test the claim that more males live with their parents using a 0.05 level of significance. Make sure you show and explain your work.

Students at a certain school were surveyed, and it was estimated that 19% of college students abstain from drinking alcohol. To estimate this proportion in your school, how large a random sample would you need to estimate it to within 0.08 with probability 0.99, if before conducting the study (a) you are unwilling to predict the proportion value at your school and (b) you use the results from the surveyed school as a guideline. a. n= b. n=

In a recent school year in the state of Washington, there were 319,000 high school students. Of these, 154,000 were girls and 165,000 were boys. Among the girls, 41,100 dropped out of school, and among the boys, 10,500 dropped out. A student is chosen at random. Round the answers to four decimal places. (a) What is the probability that the student is female? (b) What is the probability that the student dropped out? (c) What is the probability that the...

Students in a school were asked to participate in a study of the effects of a new teaching method on reading skills of 10th graders. To determine the effectiveness of the new method, a reading test was given to each student before applying the new method (pre-test). Another test was given to the same students after applying the new method (post-test). Experts consider that a good measure of improvement is given by the following formula: Improvement=20(Post-test score)- 10(Pre-test score). That...

In 2003, forty percent of the students at a major university were Business majors, 35% were Engineering majors and the rest of the students were majoring in other fields. In a sample of 600 students from the same university taken in 2004, two hundred were Business majors, 220 were Engineering majors and the remaining students in the sample were majoring in other fields. At 95% confidence, test to see whether there has been a significant change in the proportions between...
