For a 95% confidence interval, the corresponding z-score is 1.96. Therefore the deviation will by 1.96*0.5 lbs = 0.98 lbs. Therefore, the confidence interval will be (5 - 0.98, 5 + 0.98), which is (4.02, 5.98). The weight range is from 4.02 lbs to 5.98 lbs.
Answer:
A line includes the points (4, 8) and (3, 5) whose equation in slope-intercept form will be :

Step-by-step explanation:
The point slope form: 

where : m = Slope of the line

A line includes the points (4, 8) and (3, 5).The equation of the line will be:




(y=mx+c), where c is intercept at y axis.
The above equation represents slope-intercept form of the line.
For the first one it is x=1 the second one X=8
