Question 4 The lumen output was determined for each of I = 3 different brands of lightbulbs having the same wattage, with J = 7 bulbs of each brand tested (this is the number of observations in each treatment group). The sums of squares were computed as SSTr = 598.2 and SSE = 4772.5. Question 4a. ANOVA Test Homework . Answered State the hypotheses of interest. Let Mi = the true average lumen output for brand / bulbs Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a Ho : M1 = M2 = My VS. HA : at least two of the Mi's are not equal Your answer b Ho : H1 * H2 * MyVS. HA : all three Mi's are equal C Ho : M1 / M2 / M3 VS. HA : at least two of the Mi's are equal Answered - Correct! . 2 attempts left ResubmitQuestion 4b. ANOVA Test Important Homework . Answered Use the Single Factor ANOVA F test with a = 0.05 to decide whether there are any differences in true average lumen outputs among the three brands for this type of bulb. State the f statistic below. Round your answer to two decimal places. Avoid rounding at intermediate steps throughout the calculation (i.e. only round at the end). Type your numeric answer and submit 0.38 X You are incorrect Answered - Incorrect . 1 attempt left Resubmit Question 4c. ANOVA Test Homework . Answered State the p-value. Round your answer to four decimal places. Calculate the F test statistic then use R to find your p-value using the CDF of the f distribution pf(). Recall the p-value from an F test is always the area to the right of the F test statistic.
