The t-table has entries for areas of 0.10, 0.05, 0.025, 0.01, and 0.005. In contrast, the ? 2 -table has entries for those areas and for 0.995, 0.99, 0.975, 0.95, and 0.90.  Explain why the t-values corresponding to these additional areas can be obtained from the existing t-table but must be provided explicitly in the ? 2 -table.

Suppose P(A) = 0.59, P(B) = 0.28, and P(An B)= 0.01. What is P(Aª|B)? [Give your numeric response to at least 3 decimal places. Give only the number, and no extra characters or symbols.]

Suppose P(A) = 0.7 and P(B) = 0.5. If P(A and B) = 0.3, with the help of a Venn diagram, we can estimate that P(A or B) will be a) more than 0.7 b) less than 0.5 c) more than 1.2 d) less than 0.3

For Americans using library services, the American Library Association (ALA) claims that 67% borrow books. A library director feels that this is not true, so he randomly selects 101 borrowers and finds that 78 borrowed books. Can he show that the ALA claim is incorrect?

EDFN 1090/1092 Assignment #5 1. Would you expect a positive, negative, or zero correlative between each of the following pairs of variables? a. Heights of mothers and daughters b. Age and reaction time in the adult population c. Natural gas usage and prevailing (outside) temperature d. Reading skill and shoe size in the population of individuals over 18 2. A researcher hypothesized that there is a relationship between self-esteem and social responsibility, which increases with age. The researcher gave self-esteem and social responsibility inventories to two sets of people: a group of 10 high school students and 10 adults. The data collected are given below (SE = self- esteem; SR = social responsibility).
