- A) Statistics Assignment Sample

Source of Variation | Degree of Freedom | Sum of Squares | Mean Square | F-Value | P-Value |

Between Treatments | 3 | 90 | 30 | 5 | 0.022077 |

Within Treatments (Error) | 20 | 120 | 6 | ||

Total | 23 | 210 | 36 |

P-Value = 0.022077, the result is not significant at p<0.01

- B) Effect Size = Sum of Squares of error/total sum of squares

= 120/210

= 0.57

- C) From the table the total treatment = I-1=3

= 4 treatments.

Observation in each group = I (J-1) = 20

= 4(J-1) =20

=J-1=5

=J=6

Total Number of freedom = n-1 = 23

= n = 24.

**Note:** Please refer to Excel sheet for Question 2.

Mention below is the formula used
to find the a & b from which we have find **yhat**

- F-test = larger sample variance/ smaller sample variance

**Note:** For both part check the excel
sheet (a & b)

**Analysis**

**y = -0.2521x + 22.95**

F=51.09244 (df = 5)

T=correlation= -0.035269231

Here slope indicates the negative linear relationship as the price goes up by $1 the number of unit sold goes down by 0.2521x
