Suppose the round-trip airfare between Boston and Orlando follows the normal probability distribution with a mean of $387.20 and a standard deviation of $68.50. What is the probability that a randomly selected airfare between Boston and San Francisco will be more than $450?
The standard normal distribution is a normal distribution with a mean equal to zero and a standard deviation (or variance) equal to one is true?
The variance and standard deviation are the most widely used measures of central location.
A binomial random variable is defined as the number of successes achieved in the n trials of a Bernoulli process.
