14.  Find the probability P( Z < 1.79 ).     0.4633     0.0367     0.9633     0.5367

The percentage of vehicles on a freeway that violate the speed limit is π = 0.88 You randomly clock  n = 80  vehicles.   32)   The probability that between  66 and 70 vehicles violate the speed limit is   P(66 ≤ x ≤ 70) =                 a 0.4350 b 0.4438 c 0.4529 d 0.4621

Choose from the choices and show the solution.

Find the probability of z occurring in the indicated region. z = 0.67 z = 1.89 a) Based on the diagram above my probability should be less than b) The probability statement is : P ( 0.67 ✓ <= ✔ z = ✔ = ✔ 0.5000 or 50%? <= ✔ 1.89 ✓)=P( z = ✔ <= ✔ 1.89 c) The probability 0.2221 x can also be considered 22.21 *% which is less than 0.5000 or 50% of the curve. ) P( 2 ✓ = <= ✔ 0.67 = 0.2221
