If all possible samples of size 25 are drawn from a normal population with mean equal to 50 and standard deviation equal to 7, what is the probability that a sample mean upper x overbar will fall in the interval from mu subscript upper x overbarminus1.5sigma subscript upper x overbar to mu subscript upper x overbarminus0.9sigma subscript upper x overbar?

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)
