The survival times of adult mosquitoes exposed to a commonly used synthetic pesticide (Phenothrin) follows a normal distribution with a standard deviation of 15.18 seconds. A random sample of 40 mosquitoes has an average survival time of 47.5 seconds. Construct a 99% confidence interval on the mean survival time.
