01:16 O Interactive Mathematics Solution 1. What is the probability that 5 is greater than x in a normally distributed data given that the mean is 6, and the standard deviation is 0.7. M = 0.07636 P(X < 5) the first step is to find the z- score. We find that using the formula above. - z = (x − µ (mean)) / o (standard deviation) this means that For P(X<5), z = (5-6)/0.7 -1/7 = -1.42857 which is rounded up to - 1.43 Now in the table, we will look for the value of -1.4 under 3 Ad 7.00 KB/S The normal return for the z-score is usually less than, and because the function is asking for the probability of x being less than 5, this will be our final answer. s 61 2.
