(Round to 3 decimal places.)
-1.384
0.24
Step 3: Shade the area represented by
the p-value.
0.1-
Area = 0.0832
Step 4: Enter the p-value.
(Round to 3 decimal places.)
0.0832
z=- 1.384
(d) Based on your answer to part (c), choose what can be concluded, at the 0.05 level of significance, about the claim
made by the makers of the device.
O Since the p-value is less than (or equal to) the level of significance, the null hypothesis is rejected. So, there is
enough evidence to support the claim that less than 18% of professional athletes can score the top-ranking of "light
speed."
O Since the p-value is less than (or equal to) the level of significance, the null hypothesis is not rejected. So, there is
not enough evidence to support the claim that less than 18% of professional athletes can score the top-ranking of
"light speed."
O Since the p-value is greater than the level of significance, the null hypothesis is rejected. So, there is enough
evidence to support the claim that less than 18% of professional athletes can score the top-ranking of "light speed."
