121 of the green beans will be shorter than 13 centimeters.
First, we need to evaluate the expression below to find the z-score.
(13 - 11.2) / 2.1. = 0.86
The matching percent for this z-score is 0.8051.
Multiplying 0.8051 by 150 gives us about 121 green beans.
Answer: The slope is - 1/2.
Step-by-step explanation:
Y=Mx+b
Rise / run between any two points = slope (m)
Where the line crosses the y axis is (yint) (b)
Slope is -1/2
Yint = -8
So the equation is y=(-1/2)x - 8
What is the difference between selecting a member at random from a finite population and taking a simple random sample of size 1?
Solution: The correct option is d. There is no difference
<u>Explanation:</u>
Random sampling: In random sampling, each and every unit of the population has an equal chance of included in the sample.
Simple random sampling: In simple random sampling, also every unit of the population has an equal chance being included in the sample.
In the given situation, the selecting a member randomly from a finite population will be same as using a simple random sampling to select sample of size 1. Therefore, there is no difference between the two.
