Sorta Ice Cream sells a new soy based ice cream substitute. The company is convinced that 40% of people will prefer vanilla, 25% will prefer chocolate, 15% will prefer strawberry, and the rest will prefer some other flavor. Sorta is planning its daily production schedule based on these figures. In a random sample of 100 potential customers, 55 say they prefer vanilla, 20 say they prefer chocolate, 15 say they prefer strawberry, and 10 say they prefer another flavor. Is this sufficient sample evidence to question the company’s plan? Use a significance level of .05 and show the appropriate hypothesis test.
