Answer: 11.9%
Step-by-step explanation:
Given : On a stretch of Interstate-89, car speed is a normally distributed variable with mph and
mph.
Let x be a random variable that represents the car speed.
Since ,
z-score corresponds x = 73 ,
Required probability :
[using z-value table.]
Hence, the approximate percentage of cars are traveling faster than you = 11.9%
The line plot is used to show the lengths of the scrap woods using check marks above the line
<h3>How to draw the line plot</h3>From the question, we have the following frequency table
<u>Lengths Frequency</u>
2
3
1
6
1
2
2
1
Next, we plot the number line.
Such that the lengths of the scrap woods are on the x-axis while their frequencies are on the y-axis
