Final answer:

The question involves probability distributions, specifically finding the probability of a normally distributed variable, the weight of a jar of jelly, being less than its mean weight.

Step-by-step explanation:

The question posed relates to the use of probability distributions to determine the probability that a jar of jelly weighs less than 16 oz, given that the weights are normally distributed with a mean of 16 oz and a standard deviation of 0.02 oz. To find this probability, one would use a Z-score formula to convert the given weight to a Z-score and then look up the corresponding probability in a standard normal distribution table or use a calculator built for such statistical analysis. Since the mean is 16 oz, a weight less than 16 oz would be below the mean, thus we would be looking for the cumulative probability from the left-hand side of the distribution to the Z-score of the given weight, which in this case would correspond to a Z-score of -Infinity up to 0.
