A coin was flipped 78 times and came up heads 44 times. At the .10 level of significance, is the coin biased toward heads?   (a-1) H0: ππ ≤ .50 versus H1: ππ > .50. Choose the appropriate decision rule at the .10 level of significance.   Reject H0 if z > 1.282 Reject H0 if z < 1.282   multiple choice 1 a b   (a-2) Calculate the test statistic. (Carry out all intermediate calculations to at least 4 decimal places. Round your answer to 3 decimal places.)       (a-3) The null hypothesis should be rejected.   multiple choice 2 False True   (a-4) The true proportion is greater than .50.   multiple choice 3 False True   (b-1) Find the p-value. (Round your answer to 4 decimal places.)       (b-2) Is the coin biased toward heads?   multiple choice 4 No Yes
