In: Statistics and Probability
Describe a situation where you would use ANOVA by stating 1. the quantity of populations that are to be investigated, 2 a quantitative variable on these populations, 3 the sizes of samples from these populations, 4 your null hypothesis, 5 your alternative hypothesis, and 6 a significance level. Then find 7 the degree of freedom of the numerator of your F- statistic, 8 the degree of freedom of the denominator of your F- statistic, and state 9 what the P- value for your test statistic being less than your significance level would imply. Remember that you do not need to list the values of the variable for individuals in either the samples or the population, and that the values for 3 and 6 not need to be calculated, only stated
The answers contain some concepts of ANOVA as a prerequisite to help understand the problem based on the experimental example used here. Please note, Q7 and Q8 has both been typed as Q7, this is to mention so that any confusion doesn't arise. This is to clarify that both the numerator and denominator degrees of freedom have been calculated and answered in the answer sheets attached
