A) determine the critical value(s) if the test statistic. Zα=___(Use a comma to separate answers as needed. Round to two decimal places as needed.)Calculate the test statistic. Zp=____(Round to two decimal places as needed.) **Hypothesis Testing Example**Consider the following hypotheses:- \( H_0: p \leq 0.22 \)- \( H_1: p > 0.22 \)Given that \( \hat{p} = 0.3 \), \( n = 130 \), and \( \alpha = 0.01 \), answer the following questions:**a. What conclusion should be drawn?****b. Determine the p-value for this test.****Steps:**1. **Determine the critical value(s) of the test statistic:** - \( z_\alpha = \) [Input box] *(Use a comma to separate answers as needed. Round to two decimal places as needed.)*2. **Calculate the test statistic:** - \( z_p = \) [Input box] *(Round to two decimal places as needed.)*3. **What conclusion should be drawn?** - [ ] A. Reject \( H_0 \). There is sufficient evidence that \( p > 0.22 \). - [ ] B. Reject \( H_0 \). There is insufficient evidence that \( p > 0.22 \). - [ ] C. Do not reject \( H_0 \). There is sufficient evidence that \( p > 0.22 \). - [ ] D. Do not reject \( H_0 \). There is insufficient evidence that \( p > 0.22 \).4. **Calculate the p-value:** - p-value \( = \) [Input box] *(Round to three decimal places as needed.)*This example guides you through determining whether to reject or fail to reject a null hypothesis based on a given significance level, using the critical value and calculated p-value.

I need help with stats/2023, section 7.1, Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis or (b) fails to reject the null hypothesis? A report claims that more than 74% of households in a specific county struggle to afford basic necessities. Does the claim represent the null hypothesis or the alternative hypothesis? Since the claim (1) ______________ (contains or does not contain) a statement of equality, it represents the (2) ________________ (null or alternative) hypothesis.

A blind taste test is conducted to determine which of two colas, Brand A or Brand B, individuals prefer. Individuals are randomly asked to drink one of the two types of cola first, followed by the other cola, and then asked to disclose the drink they prefer. Results of the taste test indicate that 51of 100 individuals prefer Brand A. Complete all parts (a) Conduct a hypothesis test (preferably using technology) H0: p=p0 versus H1: p≠p0 for p0=0.40, 0.41, 0.42, ..., 0.60, 0.61, 0.62 at the α=0.05 level of significance. For which values of p0 do you not reject the null hypothesis? What do each of the values of p0 represent? Do not reject the null hypothesis for the values of p0 between nothing and nothing, inclusively.
