# STA408 Design and Analysis of Experiments Assignment No 01 Spring 2020 Solution & Discussion Due Date: 31-05-2020

STA408 Design and Analysis of Experiments Assignment No 01 Spring 2020 Solution & Discussion Due Date: 31-05-2020

STA408 Design and Analysis of Experiments Assignment 1 Solution & Discussion Spring 2020

Assignment No.1 (Course STA 408)

Spring 2020 (Total Marks 20)

Last date: 31-May-2020

Question 1:                                                      Marks:  10

Find the values of Sum of Squares and value of F for the given ANOVA table of Completely Randomized design.

 Source of Variation Degree of freedom Sum of squares Mean Square F Treatment 2 27.897 13.949 9.59 Error 12 17.452 1.454 Total 14 -

Total Corrected                               14                      45.349

Correction Factor                              1                        779.041

The test statistic is the F value of 9.59 is using an  of 0.5 we have that F, 0.5; 2,12 =3.89  . Since the test statics is much larger than the critical value we reject  the null hypothesis of equal population means and conclude that there is a statistically ,

Significant difference among the population means , The p-value for 9.59is 0.00325 so  the rest statistic at that level….

Question 2:                                                      Marks:  10

An experiment was performed to investigate the keyboard feel on computer (crisp or mushy) and the size of the keys (small, medium, or large). The response variable is typing speed. Three replicates of the experiment were performed. The experimental design and the data are as follow.

 Days 1st 2nd Keyboard Keyboard Key size Mushy Crisp Mushy Crisp Small 7,9 10,11 4,5 1,0 Medium 3,2 6,5 0,1 1,2 Large 0,1 1,1 1,3 6,7

If the TotalSS=809.625, Correction Factor=315.375, SSKeysize=60.75, SSDays=26.0417 and the SSKeyboard=9.375 are respectively

Calculate the SS (Keysize x Keyboard); Sum of Squares of interaction between Keysize and Keyboard.
