Evaluate the formula z = (p? - p) / sqrt(pq/n) when p? = 605 / 1680, n = 1680, p = 0.35, and q = 1 - p. z = (Round to two decimal places as needed.)

Step 1
I believe you meant z = p - p' when p' = 1 - p, since p and q are probabilities and q = 1 - p. Now, we have the values: n = 1680 p = 0.35 q = 1 - p = 1 - 0.35 = 0.65 We can now plug these values into the formula: Show more…
