A Realtor claims that no more than half of the homes he sells are sold for less than the asking price. When reviewing a random sample of 17 sales over the past year, he found that actually 10 were sold below the asking price.

Calculate a p-value for the observed sample outcome, using the normal distribution.

Use Excel to calculate the binomial probability P(X ≥ 10 | n = 17, π = .50) = 1 - P(X ≤ 9 | n = 17, π = .50).
