Answer: a. −0.41
Step-by-step explanation:
The slope for the best-fitting linear equation is given by :-
where , =sum of squared deviations from the mean of X.
= correlation between y and x in terms of the corrected sum of products.
As per given , we have
Then, the value of the slope for the best-fitting linear equation will be
Hence, the value of the slope for the best-fitting linear equation= -0.41
So the correct answer is a. −0.41 .
Given:
Machine dispenser
Average = 600 mL soda to every glass
Volumes recorded in one day (random sampling)
600.15
599.92
599.85
599.92
599.81
600.14
600.04
599.98
Average = (sum of the volumes)/(number of readings)
= 4799.81/8
Average = 599.976 mL
Therefore there is sufficient evidence to conclude that the average volume of soda dispenser is different from 600 mL.
3 1/5 = y - 12/25
Make 3 1/5 an improper fraction.
16/5 = y - 12/25
Add 12/25 to both sides.
16/5 + 12/25 = y
Make a common denominator.
80/25 + 12 / 25 = y
92 / 25 = y
3 17/25 = y
