Answer:
The slope is 3/2
Step-by-step explanation:
The first step would be to find two clear points on the graph. You cant really get an exact reading on points between values so you want to get ones that are right on the mark.
On your graph I can clearly see the points (30,60) and (50,90).
From here you just use the formula to find the slope. ((y2-y1)/x2-x1))
90-60=30
50-30=20
30/20 can then be reduced to 3/2.
Hope this made sense!
Answer:
NO.
Step-by-step explanation:
From the question, we are given a random sample of 20 automotive batteries, a confidence interval =(0.22,0.33). Also, the population standard deviation is said to be less than 0.26 hour.
The confidence interval does NOT suggest that the variation in the batteries' reserve capacities is at an acceptable level.
REASON: If you look at the confidence interval, we can see that it contains the value for the standard deviation that is 0.26 and even MORE value than 0.26.
This does not give us any suggestion that the standard deviation is less than 0.26.
