Question

In order to test H_O: p = 0.59 versus H₁: p < 0.59, use n = 150 and x = 78 as your sample proportion.

Using your TI 83/84 calculator device, find the P-value with the appropriate Hypothesis Test

Use a critical level α = 0.05 and decide to Accept or Reject H_O with the valid reason for the decision.

Answer 1

We used 1-proportion z test to calculate the p-value.

Step 1: Selection of 1-PropZTest

Step 2: Data entry

Following is screenshot of the p-value calculated using TI 84:

p-value = 0.0407

Since p-value = 0.0407 < α = 0.05, we Reject HO
