Answer: 40/2=3
Step-by-step explanation:
Answer:
a) how much difference in number of mean is 2.2
b) standard error of sample mean = 0.8
c) the test statstistical value is greater than the critical value ,hence we reject the null hypothesis. we can conclude that the treatment thus have a significant effect
Step-by-step explanation:
Answer:
y=1/3x-4
Step-by-step explanation:
1. Use the slope formula to find the slope of the two coordinates.
y2-y1/x2-x1
-2--5/6--3
3/9 = 1/3
The slope is 1/3
2. Choose one of the coordinates and plug them and the slope into the point-slope formula
y-y1=m(x-x1)
y+2=1/3(x-6)
3. Distribute and simplify.
y+2=1/3x-2
y=1/3x-4
