In a certain school, 4 levels of French are taught with 40% of the students being enrolled in level 1, 30% enrolled in level 2, 20% enrolled in level 3, and 10% enrolled in level 4. The percentage of people who enjoy their French class is 70% in level 1, 80% in level 2, 85% in level 3, and 90% in level 4.

Given that a person enjoys his/her French class, let pj be the probability that the student is enrolled in level j. Find pj for j = 1, 2, 3, 4.

(The four answers should sum to 1 altogether.)

In a certain school, 4 levels of French are taught with 40% of the students being enrolled in level 1, 30% enrolled in level 2, 20% enrolled in level 3, and 10% enrolled in level 4. The probability that a student enjoys his/her French class is C2 given level 1, 0.4 given level 2, 0.35 given level 3, and 0.20 given level 4. A student is chosen at random. (Note: use the Bayes theorem to solve the question) a. What...

A school psychologist wants to test the effectiveness of a new method of teaching French. She recruits 500 first -grade students and randomly divides them into two groups. Group 1 is taught using the new method, while Group 2 is taught via traditional methods. The same teacher is assigned to teach both groups. At the end of the year, an achievement test is administered and the results of the two groups compared. What is the response variable in this experiment?...

Suppose researchers want to know the effect of elementary school class size on students’ math scores(total score is 100), intuitively they think there exists a negative linear relationship between class size and students’ math scores. The researchers want to know the marginal effect of class size on student’s math scores. Suppose you can construct a sample that includes 4 second grade students in different elementary schools. Data have been collected on each students’ name, gender, class size( total number of...

The mathematics department is considering revising how statistics is taught. In order to see if their changes will be effective in increasing student performance, they decided to run a Simulated Experiment. Previous semesters have that 20% of students receive an A in the class, 30% receive a B, and 40% receive a C. How would you assign values so you can use a Random Digit Table to run this experiment? a) This experiment cannot be simulated using a random digit...

An education minister would like to know whether students at Gedrassi high school on average perform better at English or at Mathematics. Denoting by μ1 the mean score for all Gedrassi students in a standardized English exam and μ2 the mean score for all Gedrassi students in a standardized Mathematics exam, the minister would like to get a 95% confidence interval estimate for the difference between the means: μ1 - μ2. A study was conducted where many students were given...
