Question

In the Kruskal-wallis test for the following data, what is the conclusion about the test at .05 significance level? Suppose that each sample include at least five observations. In addition, the hypotheses are as follows: H0 : µ1 = µ2 = µ3 H1: At least one of the population mean is different from others. Select one: A. Fail to reject H0: µ1 = µ2 = µ3. B. Reject H1: At least one of the population mean is different from others. C. Reject H0: µ1 = µ2 = µ3. D. Fail to reject H1: At least one of the population mean is different from others.

Answer #1

**Please don't hesitate to give a "thumbs up" for the
answer in case the answer has helped you**

At least one of the population mean is different from others

So, we have to reject Ho due to enough evidence.

Select one:

A. Fail to reject H0: µ1 = µ2 = µ3. - false.

B. Reject H1: At least one of the population mean is different from others. - false. we reject Ho

C. Reject H0: µ1 = µ2 = µ3.- CORRECT

D. Fail to reject H1: At least one of the population mean is different from others.- false.

**Answer is C**

A Kruskal-Wallis test is conducted on and experiment that was
testing three different levels of a fertilizer on the growth of the
same variety of tomatoes. Site 1 received no fertilizer, Site 2
received low levels of fertilizer, Site 3 received high levels of
fertilizer. All sites were treated identically in terms of the
amount they are watered, time of planting, etc. A random sample of
9 mature tomatoes is selected from each site. The weights are
recorded.
The output...

Students in a business statistics course performed a completely
randomized design to test the strength of four brands of trash
bags. One-pound weights were placed into a bag, one at a time,
until the bag broke. A total of 24 bags, 6 for each brand, were
used. The data in the accompanying table give the weight (in
pounds) required to break the trash bags. Brand 1 Brand 2 Brand 3
Brand 4 32 40 33 22 38 36 33 16...

You have been asked to determine if two different production
processes have different mean numbers of units produced per hour.
Process 1 has a mean defined µ1 and process 2 has a mean defined as
µ2 . the null and alternative hypotheses are as follows:
H0 = µ1- µ2 = 0
H1 = µ1- µ2 > 0
Using a random sample of 25 paired observations, the sample
means are 50 and 60 for population 1 and 2 respectively, test the...

Let µ1, µ2, and µ3 be the means of normal distributions with a
common but unknown variance. We want to test H0 : µ1 = µ2 = µ3
against Ha : at least two µj are different, by taking random
samples of size 4 from each distributions. Let PP x1· = 28, x2· =
46, x3· = 34, and x 2 ij = 1038.

Test the following claim. Identify the null hypothesis,
alternative hypothesis, test statistic, critical value(s),
conclusion about the null hypothesis, and final conclusion that
addresses the original claim. A manual states that in order to be
a hit, a song must be no longer than three minutes and thirty
seconds (or 210 seconds). A simple random sample of 50 current
hit songs results in a mean length of 250.0 sec. Assume the
population standard deviation of song lengths is 54.5 sec....

Imagine that a friend of yours is pleased that the results of a
Kruskal–Wallis test your friend ran as part of a dissertation
turned out to be statistically significant at alpha = .05. Your
friend followed up this significant result with 15 Mann–Whitney
tests and found out that the results were also statistically
significant at alpha = .05. Suggest one (1) overall strategy to
your friend to interpret your friend's finding from the tests.
Provide a rationale for your suggestion.

Four different paints are advertised to have the same drying
times. Use the Kruskal Wallis Test – Analysis of Variance by Ranks,
to verify the manufacturer’s claim. Remember that seven samples
were tested for each of the paints. The time in minutes until the
paint was dry enough for a second coat to be applied was recorded.
Below are the results. Paint 1 Rank Paint 2 Rank Paint 3 Rank Paint
4 Rank 114 112 126 115 117 118 127...
