Choose the one alternative that best completes the statement or answers the question. The probability that an individual has 20-20 vision is 0.17. In a class of 20 students, what is the mean and standard deviation of the number with 20-20 vision in the class?

Provide an appropriate response. The produce manager at a farmer’s market was interested in determining how many oranges a person buys when they buy oranges. He asked the cashiers over a weekend to count how many oranges a person bought when they bought oranges and record this number for analysis at a later time. The data is given below in the table. The random variable x represents the number of oranges purchased and P(x) represents the probability that a customer will buy x apples. Determine the mean number of oranges purchased by a customer.

Choose the one alternative that best completes the statement or answers the question.   Assume that male and female births are equally likely and that the birth of any child does not affect the probability of the gender of any other children. Find the probability of exactly five girls in ten births.

Solve the problem. A lab orders a shipment of 100 rats a week, 52 weeks a year, from a rat supplier for experiments that the lab conducts. Prices for each weekly shipment of rats follow the distribution below:   Find the standard deviation for the lab budget for next yearʹs rat orders assuming this distribution does not change.
