Answer #1

Answer:

Given Data

a) Calculate the Within variance , by averaging the category varinces.

= 31.77

b) By calculating the variance between the sample means.

Type Type Mean Type Mean - Overall Mean
Type 1 44 4.33 16.7489
Type 2 44.1 4.43 19.6249
Type 3 30.9 -8.77 76.9129
Total 113.2867

= 56.64335

c) Determine the "Between" variance , by multiplying the answer from part b.

  

= 4 * 56.64335

= 226.5734

d) Calculate the F - statistic by dividing the answer from part c

= 7.363451

F = 7.3635

F - statistic = 7.3635

    2. An experiment was conducted to compare five treatments for reducing fever. Thirty-five patients were randomly assigned into five treatment groups. The patients' temperatures were taken two hours after receiving the treatment, and are given below. We will test the claim that there is no difference in mean body temperature among each of the five treatment groups using a 5% significance level.

    An experimenter wants to know if having a pet or friend present while taking a stressful math test helps reduce anxiety. She recruits 120 people to participate in the study and each person takes a difficult math test under a strict time limit. The participants are also randomly assigned to take the test alone, with a friend in the room, or with a therapy dog in the room. After taking the test, participants completed a survey that assessed how stressful...
