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 equals=4.
(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 chiχsquared2. (d) Find the value of chiχsquared2 for testing Upper H0 (e) Find the p-value for testing Upper H0
