In a simple random sample of 31 colored candies, it is found that none of them are blue. Use a 0.01 significance level to test the claim of the candy company that the proportion of candies that are blue is equal to 0.10. Can a hypothesis test for a claim about the population proportion be used? If so, test the claim. If not, explain why not.

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
