You wish to test the following claim at a significance level of \(\alpha = 0.005\).\[H_0: p = 0.73 \\H_1: p > 0.73\]You obtain a sample of size 493 in which there are 376 successful observations.What is the test statistic for this sample? (Report answer accurate to 2 decimal places but do not round in the middle of your calculations.)[Text Box]What is the p-value for this sample? (Report answer accurate to 4 decimal places.)[Text Box]This test statistic leads to a decision to- ∘ reject the null- ∘ accept the null- ∘ fail to reject the nullAs such, the final conclusion is that- ∘ there is sufficient evidence to conclude that the population proportion is greater than 0.73.- ∘ there is not sufficient evidence to conclude that the population proportion is greater than 0.73.- ∘ there is sufficient evidence to conclude that the population proportion is equal to 0.73.- ∘ there is not sufficient evidence to conclude that the population proportion is equal to 0.73.**Question Help:** [Message instructor] ### Hypothesis Testing ExampleThis is an example of a hypothesis testing problem.**Hypotheses:**- \( H_0: p = 0.3 \)- \( H_1: p \neq 0.3 \)**Sample Information:**- Based on a sample of 70 people, 31% owned cats.**Statistical Information:**- The test statistic is calculated as 1.537 (to 3 decimal places).- The positive critical value given is -2.33 (to 2 decimal places). Note: This seems incorrect as critical values for hypothesis tests are typically positive or matched with corresponding negative values, depending on the test type.**Decision:**Based on these calculations, the decision is to:- Fail to reject the null hypothesis.If you have questions or need further clarification, you can contact your instructor by clicking the "Message instructor" link.After reviewing, you can submit your response using the "Submit Question" button.

After clicking the Generate Results button, SALT will display the summary of the One Sample t test on the right side of the Inferential Statistics page. Enter the requested values below. Round your standard error to three decimal places and your test statistic to two decimal places. Standard Error: Test Statistic: Degrees of freedom: P-value: 0.493 66.366 53 53 less than 0.05 0.493 66.37 less than 0.05 Step 5 of 5 Since the P-value is less than our significance value of 0.05, this leads us to reject the null hypothesis. Based on the sample data, there ---Select--- convincing evidence that male Boston Marathon winners have an average finish time that is longer than the male Boston Wheelchair Marathon winners than what could have resulted from sampling error alone. In other words, Boston's male wheelchair athlete winners finish a marathon in ---Select--- time, on average, than male Boston marathon winners.

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1413 referee calls, with the result that 426 of the calls were overturned. Women challenged 742 referee calls, and 228 of the calls were overturned. Use a 0.05 significance level to test the claim that men and women have equal success in challenging calls. Identify the test statistic. z= ? (Round to two decimal places as needed.) Part 3 Identify the P-value. P-value= ? (Round to three decimal places as needed.) Part 4 What is the conclusion based on the hypothesis test? The P-value is ▼ greater than or less than the significance level of α=0.05, so ▼ fail to reject or reject the null hypothesis. There ▼ is not sufficient or is sufficient evidence to warrant rejection of the claim that women and men have equal success in challenging calls. Part 5 b.
