Final answer:
To compare two population proportions and test the null hypothesis (p1−p2)=0 against the alternative hypothesis (p1−p2)≠0 with α=0.05, a two-proportion z-test is used. The test statistic would be calculated followed by the comparison of the p-value to the significance level. The conclusion, whether to reject or not reject the null hypothesis, depends on this comparison.
Step-by-step explanation:
When comparing two independent population proportions, we are interested in determining whether there is a significant difference between the two proportions.
In this case, each sample contains 50 observations, with the first population having 35 successes and the second having 29 successes.
To test the null hypothesis H0: (p1−p2) = 0 against the alternative hypothesis Ha: (p1−p2) ≠ 0, we will use a two-proportion z-test at the 0.05 significance level.
To calculate the test statistic, we need to use the formula for the z-statistic in a two-proportion z-test. As we do not have the specific numbers, we cannot provide the exact test statistic.
However, using a calculator or software that has the 2-PropZTest function, one can find the p-value.
A p-value that is less than the significance level (α=0.05) would lead us to reject the null hypothesis.
Without the exact p-value, we can't state the final conclusion. However, the general form of the conclusion would be:
- If p-value < α, we reject H0 and conclude there is a significant difference between p1 and p2.
- If p-value ≥ α, we do not reject H0 and conclude there is not sufficient evidence to suggest a difference between p1 and p2.
The options provided for the conclusion in the question appear to be incorrectly phrased, as they do not align with the correct interpretation of hypothesis testing results.
