Use the One-Proportion Z-Test to Perform the Required Hypothesis Test

question 75

Essay

Use the one-proportion z-test to perform the required hypothesis test. Use the critical-value approach.
-An airline's public relations department says that the airline rarely loses passengers' luggage. It further claims that on those occasions when luggage is lost, 92% is recovered and delivered to its owner within 24 hours. A consumer group who surveyed a large number of air travelers found that only 145 out of 165 people who lost luggage on that airline were reunited with the missing items by the next day. At the 5% level of significance, do the data provide sufficient evidence to conclude that the proportion of times that luggage is returned within 24 hours is less than 0.92?
