1)You are given a sample size n = 10. You are asked for a 99% confidence interval. What value of t or z do you use?

Enter only the value, not the letter t or z.

2)You are given a sample size n = 29. You are asked for a 99% confidence interval. What value of t or z do you use?

Enter only the value, not the letter t or z.

3)Given that there are 68 equally likely outcomes, that event A can happen 5 ways and event B can happen 8 ways, what is the value of P(A)?

4)Given:

P(A) = 0.47;

P(B) = 0.12;

P(A or B) = .18;

Find: P(A and B)

5) Given events A and B are independent:

P(A) = 0.59

P(B) = 0.63

Find: P(A and B)-- use 3 decimal places
