ANOVA F test was conducted to test whether the means of four groups are the same against at least one group mean is different. The total number of subjects in four samples were 50. The F ratio (test statistics) was 2.45

a) What is the p-value?

b) What is your conclusion at 5% significance level? Are all group means the same?

An ANOVA test is conducted to compare three different income tax software packages to determine whether there is any difference in the average time it takes to prepare income tax returns using the three different software packages. Ten different individuals' income tax returns are done by each of the three software packages and the time is recorded for each. Because individual tax returns are different the analysis has decided to block on individual returns. The computer results are shown below....

An experiment was conducted for better understanding of the effectiveness of a particular type of drug for reducing bad cholesterol (LDL) level. The purpose of the experiment was to determine whether different dosages used have significant different outcomes in average LDL reduction. Twenty subjects with LDL at around 250 to 300 mg/dL had participated in the study and were randomly divided into four groups. Each group was given a specific level of dosage of the drug each day for one...
