5) A public bus company official claims that the mean waiting time for bus number 14 during 5) – peak hours is less than 10 minutes. Karen took bus number 14 during peak hours on 18 different occasions. Her mean waiting time was 7.6 minutes with a standard deviation of 2.3 minutes. At the 0.01 significance level, test the claim that the mean waiting time is less than 10 minutes. Use the P-value method of testing hypotheses.

Question 2 Young and Company claims that its pressurized diving bell will, on average, maintain its integrity to depths of 2500 feet or more. You take a random sample of 50 of the bells. The average maximum depth for bells in your sample is 2455 feet. Set up an appropriate hypothesis test using Young and Company’s claim as the null hypothesis. Assume the population standard deviation is 200 feet. Use a 1% significance level. a) What is the p-value that...

A manufacturer claims his light bulbs have a mean life of 1500 hours. A consumer group wants to test if their light bulbs do not last as long as the manufacturer claims. They tested a random sample of 220 bulbs and found them to have a sample mean life of 1490 hours and a sample standard deviation of 40 hours. Assess the manufacturer's claim. a) What is the null hypothesis? μ = 1500 x̄ = 1500 x̄ < 1500 μ...
