Robert claims that all Lifesavor flavors (i.e., cherry, orange, lemon, and strawberry) are equally likely to appear in packages. To test this, you collect a sample size of n= 50. Your sample contains 9 cherry, 15 orange, 14 lemon, and 12 strawberry pieces.   Perform a goodness of fit test to test the null hypothesis that all flavors are equally likely to appear versus the alternative that they are not equally likely to appear.    Once the test statistic is found, it needs to be compared to a chi-squared distribution with some number of degrees of freedom. In this example, how many degrees of freedom would that chi-squared distribution have?
