Use the α = 0.05 level of significance.
(SHOW WORK PLEASE FOR ME TO UNDERSTAND THE STEPS)
1. Compute the following
p-hat, Standard error, Critical Z, and Test Z.
2. Do you reject or fail to reject the null hypothesis. Explainwhy. Use the α = 0.05 level of significance.
3. State the null and alternative hypotheses and what type ofTEST?
4. Compute the P-value?
