Find the pvalue H1 p 0575 the test statistic is z 155 H1 p

Find the p-value: H_1: p > .0575; the test statistic is z = 1.55 H_1: p .97; the test statistic is z = -1.55

Solution

a)

This is a right tailed test, as H1 used >. Getting the right tailed area of z = 1.55,

P = 0.060570758 [ANSWER]

***************

b)

This is a two tailed test, as H1 used =/=.

Thus, multiplying the left tailed area of z = -1.55 by 2,

P = 0.121141516 [ANSWER]
