a)

Assume it is NOT a leap year. How many ways are there that no two students will have the same birth date in a class of size 60? Express the result in expression.

b)

Prove that A ∪ B = S − A’ ∩ B’, where S is the total sample space and A and B are two subsets in it. You might use the graph way.

Same Topic: 1. For a finite, equiprobable sample space S, show that P(A|B) = |A ∩ B| |B| , for any two events A, B. 2. Use the result in problem 2 to find P(A|B) where |A| = 25, |A − B| = 15, and |B − A| = 10. Note the use of the result from 2 allows us to compute this conditional probability without actually knowing the size of our sample space.

Data for this analysis was collected over many years of class. You can assume that this data represents samples selected from larger groups of students. Students in a business statistics class were asked to agree/disagree with the following statement at the end of the class: "I really enjoyed this class." A study was conducted to determine if a difference existed between the responses of students in two different teaching methods used - traditional live teaching and online teaching. The Statistix...

A class survey in a large class for first-year college students asked, "About how many hours do you study during a typical week?" The mean response of the 463 students was x = 15.4 hours. Suppose that we know that the study time follows a Normal distribution with standard deviation σ = 8.9 hours in the population of all first-year students at this university. (a) Use the survey result to give a 99% confidence interval for the mean study time...
