use a right-tailed hypothesis test for this one-sample z-test of a proportion to determine whether the difference between 0.557 and 0.54 is statistically significant at a significance level of 0.05. which of the following statements is correct?
a. the difference is not statistically significant at a level of 0.05 because the p-value is less than 0.05.
b. the difference is statistically significant at a level of 0.05 because the p-value is less than 0.05.
c. the difference is statistically significant at a level of 0.02 because the p-value is less than 0.02.
d. the difference is not statistically significant at a level of 0.05 because the p-value is not less than 0.05.
e. the difference is not statistically significant because the difference between 0.557 and 0.54 is very small.
