For a standard normal distribution, find the approximate value of cap p times open paren z is greater than or equal to negative 1 point 2 5 close paren Use the portion of the standard normal table to help answer the question. z Probability 0 point 0 0 0 point 5 0 0 0 0 point 2 5 0 point 5 9 8 7 1 point 0 0 0 point 8 4 1 3 1 point 2 5 0 point 8 9 4 4 1 point 5 0 0 point 9 3 3 2 1 point 7 5 0 point 9 5 9 9
By symmetry of the standard normal distribution, P(Z ≥ −1.25) equals P(Z ≤ 1.25). The table gives a probability of 0.8944 for z = 1.25, which is about 89%. Therefore, the correct choice is 89 percent.
