d. What is the null hypothesis and what do you conclude about it?
Identify the null hypothesis.
O A. Ho: p=0.94
O B. Ho: p*0.94
OC. Ho: p<0.94
O D. Ho:p>0.94
Choose the correct answer below.
O A. Reject the null hypothesis because the P-value is greater than the significance level, c.
B. Reject the null hypothesis because the P-value is less than or equal to the significance level, c.
O C. Fail to reject the null hypothesis because the P-value is greater than the significance level, a.
O D. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, a.
e. What is the final conclusion?
O A. There is not sufficient evidence to warrant rejection of the claim that 94% of adults own a cell phone.
