What can be conduded at the a - 0.10 level of significance?
For this study, we should use z-test for a population proportion
a. The null and alternative hypotheses would be:
Ho: Select an answer v Select an answer v Select an answer v (please enter a decimal and note that p1
and ul represent the proportion and mean
women and
and u2 represent
proportion and mean for
men.)
H: Select an answer v Select an answer v Select an answer v (Please enter a decimal)
b. The test statistic ? v
(please show your answer to 3 decimal places.)
c. The p-value =
(Please show your answer to 4 decimal places.)
d. The p-value is ? va
e. Based on this, we should Select an answer v the null hypothesis.
f. Thus, the final condusion is that ...
O The results are statistically significant at a - 0.10, so there is sufficient evidence to condude
