Find the mean difference in weights of the melons? Find the standard deviation of the difference in weights? If a Normal model can be used to describe the difference in weights, find the probability that the melon you got at the first store is heavier?

This question aims to find the value of $c$ given the probability distribution of a random variable $X$. In probability theory, a random variable is regarded as a real-valued function that is defined over a sample space of a random experiment. In other words, it describes the outcome of an experiment numerically. Random variables can […]
