PLEASE HELP
A poll of 2,008 randomly selected adults showed that 96% of them own cell phones. The technology display below results from a test of the claim that 94% 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 = 0.94 vs p # 0.94 Sample X N Sample p 95% CI Z-Value P-Value 1 1925 2,008 0.958665 (0.947223,0.970108) 3.52 0.000 a. Is the test two-tailed, left-tailed, or right-tailed? O Two-tailed test O Left-tailed test O Right tailed test b. What is the test statistic? The test statistic is. (Round to two decimal places as needed.) C. What is the P-value? The P-value is. (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 = 0.94 O B. Ho: p > 0.94 O C. 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, a. O B. Reject the null hypothesis because the P-value is less than or equal to the significance level, a. 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? A. There is not sufficient evidence to warrant rejection of the claim that 94% of adults own a cell phone. O B. There is sufficient evidence to warrant rejection of the claim that 94% of adults own a cell phone. O C. There is sufficient evidence to support the claim that 94% of adults own a cell phone. O D. There is not sufficient evidence to support the claim that 94% of adults own a cell phoneStep by Step Solution
