A survey of randomly selected adults showed that of them have heard of a new electronic reader. The accompanying technology display results from a test of the claim that % of adults have heard of the new electronic reader. Use the normal distribution as an approximation to the binomial distribution, and assume a significance level to complete parts (a) through (e). Sample proportion: Test statistic, z: Critical z: P-Value: a. Is the test two-tailed, left-tailed, or right-tailed? Right tailed test Left-tailed test Two-tailed test Your answer is correct. b. What is the test statistic? z 3.54 (Round to two decimal places as needed.) c. What is the P-value? P-value . 0004 (Round to four decimal places as needed.) d. What is the null hypothesis and what do you conclude about it? Identify the null hypothesis. A. B. C. Your answer is correct. D. Choose the correct answer below. A. the null hypothesis because the P-value is the significance level, . B. the null hypothesis because the P-value is the significance level, . C. the null hypothesis because the P-value is the significance level, . D. the null hypothesis because the P-value is the significance level, . Your answer is correct. e.
