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 man is on trial accused of murder in the first degree. The prosecutor presents evidence that he hopes will convince the jury to reject the hypothesis that the man is innocent. This situation can be modeled as a hypothesis test with the following hypotheses: Ho : The defendant is innocent. Ho: The defendant is guilty.

dlo Recovering from surgery: A new postsurgical treatment was compared with a standard treatment. Nine subjects received the new treatment, while nine others (the controls) received the standard treatment. The recovery times, in days, are given below. Treatment: 12 13 15 19 20 21 22 24 25 Control: 16 17 19 21 22 23 25 26 27 Send data to Excel Can you conclude that the mean recovery time for those receiving the new treatment is less than the mean for those receiving the standard treatment?

A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 73%. Suppose that we have reason to believe that this proportion has changed, and we wish to carry out a hypothesis test to see if our belief can be supported. State the nulIl hypothesis H, and the alternative hypothesis H, that we would use for this test. Ho' H: ] ロ-ロ
