Question

Problem #8: Consider the following data 30,23,39, 40,28, 38,34 (a) If you were to construct a normal probability plot by hand for the above data what are the numerical values (in order) of the first five numbers that would go on the x-axis? Separate your answers with a comma. (Read the last two pages of this example for a description of the normal probability plot.) For example, if your data was the same as the last page of this example then you would enter the following numbers from Step 4 (on the last page) into the answer box (note that spaces don't matter) 4, 4, 7, 7, !9 (b) If you were to construct a normal probability plot by hand for the above data what are the numerical values (in order) of the first five numbers that would go on the y-axis? Separate your answers with a comma. (See the last two pages of this example for a description of the normal probability plot.) For example, if your data was the same as the data on the last page of this example then you would enter the following numbers from Step 4 (on the last page) into the answer box (note that spaces don't matter): 1.83, -1.28, -0.97, -0.73, -0.52 Problem #8(a): first five x-values first five y-values (answers rounded to 2 decimals) Problem #8(b) Just Save Submit Problem #8 for Grading Problem #8 | Attempt #1 | Attempt #2 | Attempt #3 Your Answer: 8(a) 8(b) Your Mark: |8(a) 8(b 8(a) 8(b) 8(a) 8(b 8(a) 8(b) 8(a) 8(b

Explanation / Answer

Using this we will calculate the required data

a. Based on above description values on x axis is ordered value

23   28   30   34   38   39   40

b. We will calculate below table

Hence the last column means z values will be on y axis

x Position fi=(i-0.375)/(n+0.25) z=NORMSINV(fi) 30 1 0.086206897 -1.364488748 23 2 0.224137931 -0.758292557 39 3 0.362068966 -0.352933986 40 4 0.5 -1.39214E-16 28 5 0.637931034 0.352933986 38 6 0.775862069 0.758292557 34 7 0.913793103 1.364488748
