Calculate the test statistic, z 0. z 0equals nothing (Round to two decimal places as needed.) Identify the P-value. P-valueequals nothing (Round to three decimal places as needed.) Choose the correct result of the hypothesis test for the P-value approach below. A. Do not reject the null hypothesis, because the P-value is greater than alpha. B. Reject the null hypothesis, because the P-value is less than alpha. C. Do not reject the null hypothesis, because the P-value is less than alpha. D. Reject the null hypothesis, because the P-value is greater than alpha.

Answer #1

sample success x = | 140 | ||

sample size n = | 250 | ||

std error σp =√(p*(1-p)/n) = | 0.0316 | ||

sample prop p̂ = x/n=140/250= | 0.5600 | ||

z =(p̂-p)/σp=(0.56-0.5)/0.56= |
1.90 |
||

p
value
= |
0.029 |
(from excel:1*normsdist(-1.9) |

since p value >alpha:

**A. Do not reject the null hypothesis, because the
P-value is greater than alpha.**
