I have a dataset with 140 observations on 3 different color of diamonds to see if color impacts how many carats they are cut to.
Which of the following would be the correct alternative hypothesis.
Group of answer choices
At least one of the means does not equal 0
The proportions are different for different groups.
The means are all different
At least one of the means is different
Homework Answers
Answer:
At least one of the means is different.
Explanation:
The null and alternative hypotheses for the given scenario are given as below:
Null hypothesis: H0: All means are same.
Alternative hypothesis: Ha: At least one of the means is different.
H0: µ1 = µ2 = µ3 versus Ha: At least one µ’s different.

1. Forty refrigerators from two different models of a refrigerator manufacturer are compared to see if the smaller model uses less energy than the larger model. The energy was measured in kilowatt hours per month (kwh/mo). From years of testing these models, it is known that the standard deviation of kwh/mo is 34 kwh/mo for the smaller model and 40 kwh/mo for the larger one. From this survey, the sample means and standard deviations are 125 and 34, and 90...

In order to compare the means of two populations, independent random samples of 400 observations are selected from each population, with the results found in the table to the right. Complete parts a through e below. Sample 1 overbar x = 5,305 s1= 154 Sample 2 overbar x = 5,266 s2 = 199 a.
