Obtain the value of the random variable X if the Z-score equals 1.50.
The value of the random variable X if the Z-score equals 1.50 is obtained below as follows:
Let X denotes the random variable with the population mean of 100 and standard deviation of 20.
That is, μ=100, σ=20.
The required value of X is,
z=Xμσ
1.50=X10020
X100=1.50×20=30
X=100+30=130
The value of the random variable X if the Z-score equals 1.50 is 130.

The scatter plot below shows the average cost of a designer jacket in a sample of years between 2000 and 2015. The least squares regression line modeling this data is given by y^=4815+3.765x. A scatterplot has a horizontal axis labeled Year from 2005 to 2015 in increments of 5 and a vertical axis labeled Price ($) from 2660 to 2780 in increments of 20. The following points are plotted: (2003,2736),(2004,2715),(2007,2675),(2009,2719),(2013,270). All coordinates are approximate. Interpret the y-intercept of the least squares regression line. Is it feasible? Select the correct answer below: The y-intercept is −4815, which is not feasible because a product cannot have a negative cost. The y-intercept is 3.765, which is not feasible because an expensive product such as a designer jacket cannot have such a low cost. The y-intercept is −4815, which is feasible because it is the value from the regression equation. The y-intercept is 3.765 which is feasible because a product must have a positive cost.
