A certain drug is used to treat asthma. In a clinical trial of the drug, 18 of 282 treated subjects experienced headaches (based on data from the manufacturer). The accompanying calculator display shows results from a test of the claim that less than 11% of treated subjects experienced headaches. Use the normal distribution as an approximation to the binomial distribution and assume a 0.05 significance level.

The manager of a computer retails store is concerned that his suppliers have been giving him laptop computers with lower than average quality. His research shows that replacement times for the model laptop of concern are normally distributed with a mean of 4.4 years and a standard deviation of 0.6 years. He then randomly selects records on 38 laptops sold in the past and finds that the mean replacement time is 4.1 years. Find the probability that 38 randomly selected laptops will have a mean replacement time of 4.1 years or less. Round your answer to four decimal places.P(M≤4.1 years)=P(M≤4.1 years)= Based on the result above, does it appear that the computer store has been given laptops of lower than average quality? No. The probability from the sample shows it is unlikely that the owner is given laptops lower than average quality. Yes. The probability from the sample shows that there's a possibility that the owner is given laptops lower than average quality.
