Question

A lower tail area should be found since the test statistic, z = -1.39, is negative. The area under the curve to the left of a z-value corresponds to the lower tail area. Recall that the standard normal table gives the area to the left of z-values and the entire area under the curve is 1. Use the standard normal table to find the lower tail area for z = -1.39, rounding the result to four decimal places. area to the left of -1.39 = .0823 0.0823 Step 5 The lower tail area for the test statistic z = -1.39 was found to be 0.0823. To find the p-value associated with this test statistic, multiply this area by 2, rounding the result to four decimal places. p-value = 2(lower tail area) = 2( ) =

Use the standard normal table to find the lower tail area for z = -1.39, rounding the result to four decimal places.

area to the left of -1.39 = .0823 0.0823

Step 5
The lower tail area for the test statistic z = -1.39 was found to be 0.0823. To find the p-value associated with this test statistic, multiply this area by 2, rounding the result to four decimal places.
p-value = 2(lower tail area)
= 2( )
=
