Step 4 Thus, we have P(0 sz s 3)-(3) - (0). From part (a), we have the cdf value (0) = 0.5, the area to the left of the mean z = μ = 0. Using Table A.3 in the appendix, the value of 0(3) is determined by finding the table entry marked 3.0 and the corresponding column marked .00. This gives us (3) = Use these cdf values to compute the probability, rounding your answer to four decimal places. P(0 ≤ Z ≤ 1) = (3) - (0) -0.5

WebAssign -XCO 10. Step 4 Thus, we have P(0 ≤ Z≤ 3) = (3) - (0). From part (a), we have the cdf value (0) = 0.5, the area to the left of the mean z = μ = 0. Using Table A.3 in the appendix, the value of (3) is determined by finding the table entry in the row marked 3.0 and the corresponding column marked .00. This gives us (3) = Use these cdf values to compute the probability, rounding your answer to four decimal places.
