help solve 9e simple and easy to understand

9. Suppose that a restaurant's Customer Satisfaction (a score anywhere between 5 and 5) process [wrt RE = \"Nature generates a customer and their visit scenario\"] can be modeled as N(2,0.8). Define the Customer Rating as Y= 10X+50, where X isthe Customer Satisfaction score. 9(a). What is the mean and standard deviation of the Customer Rating process Y: RE ? mean(Y: RE) = sd(Y: RE) = 9(b). What is the distribution of the Customer Rating process, insymbols, dist(Y: RE) ? If ithas a NAMED distribution, you need only name it and give the values of parameters that identify the distribution completely. 9(c). Give a graphical representation of the process distribution dist(Y: RE). Hint: Here, Y: RE is a continuous variate process, so the Density Curve (or PDF) characterizes this distribution. Draw this density curve, with a horizontal axis that includes at least 7 accurately located and labeled tick marks. 9(d). What are the chances that a customer gives a Customer Rating value greater than 90? Parr ( 90) = 9(e). Compute g(0.25, Y: RE), the 25" percentile of the Customer Rating (Y: RE) process. 9(f). Fillinthe blank. If RE were independently repeated a trillion times, then about 25% of the trillion Customer Rating values will be less than or equal to
