Using the formula for a one - proportion Zstatistic, the value of the test statistic would be 6.83
The test statistic can be defined thus :
Test statistic = [(Phat - P0) ÷ √(pq/n)]
Test statistic = [(0.65 - 0.50) ÷ √(0.5 × 0.5)/519)]
Test statistic = 0.15 ÷ √0.0004816
Test statistic = 6.834
Therefore, the test statistic would be 6.83.
