Question 14 (of 16) ' I Save & Exit Submit 6.25 points A coin was flipped 12 times and came up heads 9 times. (a) The assumption of normality is justified. Yes No (b-1) Calculate a p-value for the cbserved sample outcome, using the normal distribution. (Round your z- value to 2 decimal places. Round your answer to 4 decimal places.) p-value (b-2) At the 0.05 level of significance in a right-tailed test, is the coin biased toward heads? Yes O No (c) Use Excel to calculate the binomial probability P(X29 I n = 12, = 0.50)-1-PlX$ 1 n = 12, = 0.50). (Round your answer to 4 decimal places.) (d) The normal probability is An approximation. O The same as the binomial probability.
