A vice president of operations is trying to determine if a new software system will increase productivity for the company. The vice president randomly selects four divisions to participate in the study. Two of the divisions (i. e., groups) receive the new software and two of the divisions (i. e., groups) do not receive the new software. There is a total of 20 teams involved in the study (5 teams per division). As a result, the vice president has a total of 4 groups with an overall sample size of n = 20.
A business analyst collects the productivity data from the 4 groups (20 teams) and conducts an ANOVA test. The business analyst identifies the F-critical value to be 3.24 at the α = 0.05 level of significance. The value for the sum of squares treatment = 135; the value for the sum of squares total = 340. Answer the following 4 questions related to this scenario:
1. The value for the mean square treatment = .
2. The value for the mean square error = .
3. The value for the F-test statistic = .
4. Is there a significant difference in productivity (α=0.05) between at least two groups?

1 1/7 hope i

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7

question: use the following table of a school bus during morning pickups to calculate its average speed between 2.8 km and 4.2 km

answer: 42 km/h

explanation: 1.4/0.033 42.42424 = 42 km/h

the best estimate is 3 because   8 can only go into 24 3 times

d: (13,-1)

step-by-step explanation:

we know the starting point is (1,5)

the ending point is (x,y)   (cristians house)

the total distance is 6 units (5: 1)  

the fast food restaurant is at (11,0) and is 5/6ths of the way from the starting point to the ending point

ending minus starting point * 5/6   is how far they went

(x-1) *5/6, (y-5) * 5/6

we then need to add the starting point to determine the location

5/6(x-1) + 1, (y-5) * 5/6 + 5

this equals the fast food location of 11,0

setting the x locations equal

5/6 (x-1) +1 =11

subtracting 1 from each side

5/6 (x-1) +1-1 =11-1

5/6(x-1) =10

multiplying by 6/5 on each side

6/5*5/6(x-1) = 10*6/5

x-1 =12

add 1 to each side

x-1+1 =12+1

x=13

do the same for the y coordinate

(y-5) * 5/6 + 5 =0

subtract 5 from each side

(y-5) * 5/6 + 5-5 =0-5

5/6 (y-5) = -5

multiplying by 6/5 on each side

6/5*5/6 (y-5) = -5 *6/5

y-5 = -6

add 5 to each side

y-5+5 = -6+5

y=-1

the ending point , or the coordinates of cristians house is

(13,-1)
