1. The analysis of variance of a completely randomized, two-factor experiment led to the following results. SS Source of Variation Factor A Factor B Interaction Error Total 64.13333 3328.133 2520.933 417.6 6330.8 MS 32.0667 1664.07 630.233 11.6 2.764368 143.454 54.33046 1.1. Interpret these results, discussing what factors have a significant effect on the response variable. Use a significance level of 0.05. (5 points)

Suppose you are comparing three population means using a one-way completely randomized design and you get the following multiple comparison results: All-Pairwise Comparisons Test of Mileage by Model Group Mean Homogeneous Groups 2 44556 A 1 31815 B 3 28435 B What conclusion would you make about the means?
When using a completely randomized design (one-way analysis of variance), the calculated F statistic will decrease as O The total variability decreases O The vanability among the groups decreases relative to the vanability within the groups O The total variability increases O The vanabamty among the groups Increases velative to the vanablity within the groups The variabiity among the 10. The least squares regression line minimizes the sum of the O Squared differences between actual and predicted Xvalues O Squared...

Hi, I needed some help with question 20.
thanks!
For problems 17 through 19, choose the appropriate level of measurement is. Choose from a) nominal b) ordinal o interval 1) Temperatures in Celsiuts at various depths of the ocean 18) Weights of m&ms in grams 19) Cntic ratings of movies on a scale from O stars to 4 stars 20) A consumer magazine wants to compare the lifetimes of ballpoint pens of three diferent toe (brand A, brand B, and...
please do it carefully
thanks for solving
thank you so much
Q1: In a completely randomized experimental design, 7 experimental units were used for each of the 5 different levels of treatments: Degrees of Freedom Mean Square Source of Variation Sum of Squares Between Treatments Error (Within 22.3 Treatments) 30.5 (A) (0) (G) 10 Total (0) a. Complete the above ANOVA table by computing the values of (A) to. b. At Q -0.05, test the hypothesis that the population treatment...
