The amounts of nicotine in a certain brand of cigarette are normally distributed with a mean of 0.903 g and a standard deviation of 0.308 g. The company that produces these cigarettes claims that it has now reduced the amount of nicotine. The supporting evidence consists of a sample of 48 cigarettes with a mean nicotine amount of 0.832 g. Assuming that the given mean and standard deviation have NOT changed, find the probability of randomly selecting 48 cigarettes with a mean of 0.832 g or less. P(M < 0.832 g) Enter your answer as a number accurate to 4 decimal places. NOTE: Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.
