Round your answers to one decimal place. Green(Lime) Orange Purple(Grape) Red(Strawberry) Yellow(Lemon) Color Flavor (b) Are the expected counts large enough for a chi-square test?(c) How many degrees of freedom do we have for this test?(d) Calculate the chi-square test statistic. Round your answer to two decimal places.(e) Determine the p-value. Round your answer to three decimal places.(f) Using a 5% level, do we find evidence that method of choice affects which is chosen?
