The daily high temperatures were recorded at an Antarctic weather station. If a temperature of -38.2 degrees Celsius is 2 units of standard deviation below the mean temperature, and a temperature of -22.6 degrees Celsius is 4 units of standard deviation above the mean, which of the following temperatures is 3 unit of standard deviation above the mean?  Pick:
A) -35.6 degrees Celsius  B) -33.0 degrees Celsius  C) -30.4 degrees Celsius  D) -27.8 degrees Celsius  E) -25.2 degrees Celsius
Let us suppose mean = M and SD = d.   So, we are given M - 2d = -38.2   and M + 4d = -22.6   solving both the equations, we will get M = -33 an d = 2.6   So, we need to find out M + 3d = -33 +3* 2.6 = -25.2. Hence, -25.2 degrees Celsius
