a. What is the null hypothesis?

H0: There is no significant difference in the mean of four treatments

b. What is the alternative hypothesis?

H1: There is significant difference in the mean of four treatments

c. Identify the value of the test statistic

Test Statistic F=6.141270387

d. Find the critical value for a 0.05 significance level

Critical value F(3,16 ) = 3.239

e. Identify the P-value

p value = 0.0055664528

f. Based on the preceding results, what do you conclude about equality of the population means?

Since the p value is less than the significance value, we reject the null hypothesis that the effect of four treatments are equal
