In a newspaper's survey of 484 people, 54.3% said that we should replace passwords with biometric security, such as fingerprints. The accompanying Statdisk display results from a test of the claim that half of us say that we should replace passwords with biometric security. Use the normal distribution as an approximation to the binomial distribution. Use the display and a 0.10 significance level to complete parts (a) through (e). Sample proportion: 0.5433884 Test Statistic, z: 1.9091 Critical z: ± 1.6449 P-value: 0.0563 a. Is the test two-tailed, left-tailed, or right-tailed? Choose the correct answer below. left-tailed two-tailed Oright-tailed b. What is the test statistic? z= 1.91 (Round to two decimal places as needed.) c. What is the P-value? P-value= (Round to three decimal places as needed.) Clear all Check answer
