Using the 0.05 significance level conduct a test of hypothesis
to determine whether the block or the treatment means differ.
|
a. |
State the null and alternate hypotheses for treatments. |
|
|
|
|
H0 |
(Click to select)The standard deviations are different.The
means are the same.The standard deviations are the same.The means
are different. |
H1 |
(Click to select)The means are the same.The standard deviations
are the same.The standard deviations are different.The means are
different. |
|
b. |
State the decision rule for treatments. (Round your
answer to 1 decimal place.) |
|
|
(Click to select)Reject / Do not reject
H0 if the test statistic is greater than . |
c. |
State the null and alternate hypotheses for blocks.
(Round your answer to 1 decimal place.) |
|
|
|
|
H0 |
(Click to select)The means are the same.The standard deviations
are the same.The standard deviations are different. Atleast one
mean is different. |
H1 |
(Click to select)The means are the same.The standard deviations
are the same.The standard deviations are different.At least one
mean is different. |
|
Also, state the decision rule for blocks. |
(Click to select)Reject/Do not reject H0 if the test
statistic is greater than . |
d. & e. |
Compute SST, SSB, SS total, and SSE and complete an ANOVA table.
(Round SS, MS values to 3 decimal places, F value
to 2 decimal places and Total to 4 decimal places.)
