A friend claims he can predict the suit of a card drawn from a standard deck of 52 cards. There are four suits and equal numbers of cards in each suit. The parameter, p, is the probability of success, and the null hypothesis is that the friend is just guessing.

a. Which is the correct null hypothesis?

i. p = 1/4        

ii. p = 1/13        

iii. p > 1/4        

iv. p > 1/13

b. Which hypothesis best fits the friend’s claim? (This is the alternative hypothesis.)

i. p = 1/4        

ii. p = 1/13        

iii. p > 1/4        

iv. p > 1/13
