A recent study was conducted to investigate the duration of time required to complete a certain manual dexterity task. The reported mean
was 10.2 seconds with a standard deviation of 16.0 seconds. Suppose the
reported values are the true mean and standard deviation for the
population of subjects in the study. If a random sample of 144 subjects is k
selected from the population, what is the approximate probability that the
mean of the sample will be more than 11.0 seconds? *
