steposvetlana [31]

Answer:

Following are the solution to the given point:

Step-by-step explanation:

Grade of students:

Grade of student:

In point a:

Grade of 9^{th} students:

\to n= 6\\\\\to Mean = \frac{ \sum x_i}{n} \\\\

               = \frac{ 5+1+2+5+2+8}{6}\\\\ = \frac{24}{6}\\\\ = 4

\to Variance\\\\\sigma^2 = \frac{\sum(x_i -\bar{x})^2}{n-1}

    =\frac{1}{5}(10)\\\\=2

\to Standard \ deviation ( \sigma) :\\\\= \sqrt{\sigma^2}\\\\= \sqrt{2}\\\\= 1.141

Since the Grade of 9^{th} student's variance is higher than 12^{th}grade,  

In point b:

Please find the attached file.

The plot above shows that the student of the ninth grade is spread more widely, as the student from 0-8 to 12 is from 0-4.
