A type of new car is offered for sale with 4 option packages. A customer can buy any number of these, from none to all 4. A manager proposes the null hypothesis that customers pick packages at random, implying the number of packages bought by a customer should be binomial with n=4. This table shows the number of packages chosen by 400 customers. (a) Find the binomial parameter p needed to calculate the expected counts. (b) Find the estimated probability that a customer picks one option. (c) Find the degrees of freedom for Packages 1 2
