Jason wants to perform a two-tailed test for equality between two independent sample proportions. Each sample has at least 10 \"successes\" and 10 \"failures.\" Jason\'s test statistic is -1.44. What is his p-value?

a .1498

b .0749

c .9251

d Between .01 and .05

Solution

Getting the left tailed area of z = -1.44, by table/technology,

P(z<-1.44) = 0.0749337

Hence, the two tailed area is twice this,

P(two tailed) = 0.1498 [ANSWER, A]
