A poll of 2,016 randomly selected adults showed that 96% of them own cell phones. The technology display below results from a test of the claim that 91% of adults own cell phones. Use the normal distribution as an approximation to the binomial distribution, and assume a 0.01 significance level to complete parts (a) through (e). Test of p=0.91 vs p *0.91 Samplex N Sample p 95% CI Z-Value P-Value 1 1931 2,016 0.957837 (0.946309,0.969366) 7.51 0.000 (Round to three decimal places as needed.) d. What is the null hypothesis and what do you conclude about it? Identify the null hypothesis. O A Ho: p<0.91 B. Hop:0.91 0 C, Hg: >0.91 D. Ho: p=0.91 Choose the correct answer below. O A Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, c. OB. Fail to reject the null hypothesis because the P-value is greater than the significance level, o.. c. Reject the null hypothesis because the P-value is less than or equal to the significance level, ce OD. Reject the null hypothesis because the P-value is greater than the significance level, c. e. What is the final conclusion? OA. There is not sufficient evidence warrant rejection of the claim that 91% of adults own a cell phone. OB. There is not sufficient evidence to support the claim that 91% of adults own a cell phone. OC. There sufficient evidence warrant rejection of the claim that 91% of adults own a cell phone. OD.
