Question 1157370: You are conducting a study to see if the proportion of women over 40 who regularly have mammograms is significantly more than 55%. With H1 : p
>
55% you obtain a test statistic of
z
=
2.229
. Find the p-value accurate to 4 decimal places.

2.229 is the z-value of the test-statistic in a 1-way test, so the p-value is the area to the right of +2.229, and that is 0.0129
If it were a two-way test, you would have to double that value.
