A poll of 2,009 randomly selected adults showed that 95% of them own cell phones. The technology display below results from a test of the claim that 92% of adults own cell phones. Use the normal distribution as an approximation to the binomial distribution, and assume a 0.05 significance level to complete parts (a) through(e). Test of p=0.920.92 vs p≠0.92 Sample=1, X=1915 N=2,009, Sample p=.953211, 95%CI (.943976, .962445), Z-Value=5.49P-Value=0.000
Is the test two-tailed, left-tailed, or right-tailed?
What is the test statistic?
What is the P-value?
What is the null hypothesis and what do you conclude aboutit?
Choose the correct answer below.
A. Reject the null hypothesis because the P-value is less than or equal to the significance level, alphaα.
B. Fail to rejectFail to reject the null hypothesis because theP-value is greater than the significance level, alphaα.
C. Fail to rejectFail to reject the null hypothesis because theP-value is less than or equal to the significance level, alphaα.
D. Reject the null hypothesis because the P-value is greater than the significance level, alphaα.
