Question:
The following data are from a completely randomized design.
Treatment | ||
A | B | C |
120 | 136 | 162 |
126 | 142 | 142 |
145 | 124 | 174 |
138 | 156 | 148 |
140 | 152 | 145 |
Question:
a. Determine the sample mean. (weight 10)
b. Determine the variance of the three sample means. (weight 10)
c. Determine the sum of squares between treatments. (weight 10)
d. Determine the mean square between treatments. (weight 10)
e. Determine the sum of squares due to error. (weight 10)
f. Determine the mean square due to error. (weight 10)
2. Net assets for the 50 packaged beverage companies represent a median value of $ 10 million. Examples of 10 carbonated beverage companies from 50 packaged beverage companies are as follows:
Company | Net Asset ($ million) |
A | 6.1 |
B | 11.7 |
C | 22.4 |
D | 9.6 |
E | 9.6 |
F | 14.5 |
G | 15.0 |
H | 6.6 |
I | 6.9 |
J | 4.9 |
Using the median, can we conclude that the ten carbonated beverage companies have less net assets than packaged beverage companies' net assets? Use = 0.05.
a. What is the hypothesis for this test? (weights 20)
b. Determine the p-value? What's your conclusion? (weights 20)
