Check your graph prediction. In Frame 4, click the view icon and select Plot View. You may click on any graph point to see the t and x values displayed. (Clicking a graph point also jumps the video to the frame for that data and highlights data for that point in any data tables.) How does the graph compare with your prediction? ANSWER:The graph is as I predicted. It is nearly a straight line with a positive slope.

a) z = -2.15 has p-value = 0.0158

b) z = -0.93 has p value = 0.1762

Step-by-step explanation:

We are given two z-scores and two p-values and we have to identify which p-value belongs to which z-score without using any calculator/table.

To solve this problem we need to understand about the p-value of the z-score and what does it represent. The p-value of a z-score represents the area under the graph in a standard normal curve which is to the left of that z-score. If the z-score is increased, the area to its left will increase, so this means the p-value will also increase.

From the given z-scores, z = - 2.15 is smaller than z = - 0.93. This means the area to the left of z = - 2.15 in a standard normal curve will be lesser than that of z = - 0.93. Hence, the p-value for z = - 2.15 will be lesser than the p-value of z = - 0.93

So,

p-value for z = - 2.15 is p = 0.058

and

p-value for z = 0.1762 is p = 0.1762
