Pepsi Pepsi Pepsi Three students volunteer for a taste test comparing Coke and Pepsi. Each student tastes samples in two identical-looking cups and decides which beverage he or she prefers. Assume that the students make selections independently of one another. Suppose the probability of picking Pepsi is 3/5 and the probability of picking Coke is 2/5 for all three students. The tasters are referred to as first, second and third. One possible outcome of the experiment is that the first and second students pick Pepsi and the third student picks Coke. The probability of this occurring is 35 х 35 х 25. Let the random variable x equal the number of Pepsi selections for any given outcome of the experiment

A student randomly selects 10 paperbacks at a store. The sample standard deviation is $1.50. Construct a 95% confidence interval for the population standard deviation, o. Assume the data are normally distributed. Don't write the dollar sign in your answers. Lower = Upper =

Suppose you have a distribution with a mean equal to 10, median equal to 20, and mode equal to 30. Positive skew, negative skew, or no skew?

Refer to the accompanying table, which describes results from groups of 8 births from 8 different sets of parents. The random variable x represents the number of girls among 8 children. Find the mean and standard deviation for the number of girls in 8 births. Click the icon to view the data table. The mean is u= girl(s). (Round to one decimal place as needed.) The standard deviation is o = e# girl(s). (Round to one decimal place as needed.)
