Question

1. Using proper notation, write the null and alternative hypothesis statements.

2. Conduct the ANOVA test (Stat à ANOVAà One Way à Compute!). Include your results here.

3. In the context of the problem posed, interpret the results of the test at the 5% significance level and make a conclusion about the hypotheses.

Hint: To correctly write hypothesis statements, you will need to use subscripts (sinking letters). This is button that allows you to insert a subscript in Word. If you have a different version of Word, or if you have a Mac, you may need to search your program’s Help. You may also want to review the Chapter 10 Handout!

Answer 1

1:

2:

Following is the output of one way ANOVA generated by excel:

3:

The p-value of ANOVA is 0.0000

Since p-value is less than 0.05 so we reject the null hypothesis.

That is there is evidence that at the 5% significance level that at least one population mean is different.
