a. In this ANOVA analysis, what are we trying to determine about the three populations they’re taken from?
b. State the null and alternate hypotheses for a three-sample ANOVA analysis.
c. What sample statistics must be known to conduct an ANOVA analysis?
d. In an ANOVA test, what does an F test statistic lower than its critical value tell us about the three populations we’re examining?

Step 1
It is given that there are three samples involve in the ANOVA. Therefore,
a).
The ANOVA is a technique which is used to determine whether the population of more than two groups are significantly different or not.
Here, there are 3 sample groups available in the ANOVA, it means that the population means would be 3 as well.
Thus, for the given case, we are trying to determine whether these three population groups' means are significantly different or not.

Step 1
b).
As per the above,
Consider that are the population means for these 3 samples.
Thus, the null and alternate hypotheses are:
${H}_{0}:{\mu }_{1}={\mu }_{2}={\mu }_{3},$
${H}_{1}:$(At least one mean is different)
