Calculate a p-value for the observed sample outcome, using the normal distribution. (Round your z-value to 2 decimal places. Round your answer to 4 decimal places.)
Use Excel to calculate the binomial probability P(X ≥ 7 | n = 12, = 0.50) = 1 - P(X ≤ 6 | n = 12, = 0.50). (Round your answer to 4 decimal places.)
