Question

Please answe before 9:30

With the recent quarantine, 30 random samples of individuals from five different cities were asked how much time they had been spending per day watching TV. If it was found that the SST = 6553 and the SST = 9875, then fill out the table below (not all squares have blanks!). Whole numbered answers may be left as such, all else should be rounded to one decimal place. Mean Source DF Sum of squares F Pr>F squares Treatment 6553 MST <0.0001 Error MSE Total 9875 What would be the correct null and alternative hypothesis for the above situation?Type the correct letter here: a. Ho: The hours of TV watched per day is dependent on the city. H.: The hours of TV watched per day is independent of the city. b. Ho: 11 = y2 = 143 Hailly & Mr 7 m c. Ho: Hi = H2 H3 Ha: at least one mean is different d. Ho: P1-P2 P3 He: at least one proportion is not equal e. Ho: P: - P2 Ho: P1 P2

Answer 1

Here, K = No. of treatments = 5
Total no. of observations = N = 30

Source	DF	Sum of squares	Mean squares	F	Pr > F
Treatment	K-1 = 4	6553	1638.25	12.328793	<0.00001
Error	N-K = 25	3322	132.88
	N-1 = 30	9875

The correct hypothesis is given by the alternative : (a).
This is because all other options just talks about three or less than three treatments whereas our question consists of 5 treatments.
