Above are the results of a drug trial. The scores are given for subjects in three different conditions – a placebo control, 5 mg and 10 mg of the drug. Please run the appropriate test in SPSS using p-value or traditional hypothesis testing method and choose the alpha or p-value. If the results are statistically significant, please perform 2 post hoc tests of your choosing.

Solutions

Expert Solution

The hypothesis being tested is:

H0: µ1 = µ2 = µ3

Ha: Not all means are not equal

The SPSS output is:

The p-value is 0.000.

Since the p-value (0.000) is less than the significance level (0.05), we can reject the null hypothesis.

Therefore, we can conclude that the results are statistically significant.
