**Confidence in Banks**A news poll conducted in 2012 asked a random sample of 1217 adults in the United States how much confidence they had in banks and other financial institutions. A total of 160 adults said that they had a great deal of confidence. An economist claims that greater than 11% of U.S. adults have a great deal of confidence in banks. Can you conclude that the economist's claim is true? Use both \(\alpha = 0.05\) and \(\alpha = 0.10\) levels of significance and the critical value method with the table.### Part 1 of 5**State the appropriate null and alternate hypotheses.**\[H_0: p = 0.11\]\[H_1: p > 0.11\]This hypothesis test is a **right-tailed** test.### Part 2 of 5**Find the critical values. Round the answer to three decimal places.**- For \(\alpha = 0.05\), the critical value is \[1.645\].- For \(\alpha = 0.10\), the critical value is \[1.282\].### Part 3 of 5**Compute the test statistic. Do not round intermediate calculations. Round the answer to two decimal places.**\[z = 2.39\]### Part 4 of 5**Determine whether to reject \(H_0\).**- At the \(\alpha = 0.05\) level, \[Choose one: (Reject/Fail to reject)\] the null hypothesis \(H_0\).- At the \(\alpha = 0.10\) level, \[Choose one: (Reject/Fail to reject)\] the null hypothesis \(H_0\).### Part 5 of 5Explanation of the decision based on the significance levels and the critical values. (Note: The values in brackets are placeholders and should be replaced with the appropriate decision, whether to reject or fail to reject the null hypothesis.)

We have given that Sample size N=1217 , favorable cases X=160 Sample proportion p^=X/N
