In the research, it should be noted that this is a Proportion, because worry or not worry is categorical
<h3>What is a proportion?</h3>
A population proportion is the percentage of the population that possesses a particular trait.
For illustration, suppose there are 1,000 people in the population and 237 of them have blue eyes. There are 237 blue eyed people out of every 1,000 people, or 237/1000.
Therefore, it should be noted that this is a Proportion, because worry or not worry is categorical.

</span>"Bisect<span>" means to divide into two equal parts which is true for the altitude of a triangle.</span>
Answer:
23 chalkboards
Step-by-step explanation:
Given:
Mean length = 5 m
Standard deviation = 0.01
Number of units ordered = 1000
Now,
The z factor = 
or
The z factor = 
or
Z = - 2
Now, the Probability P( length < 4.98 )
Also, From z table the p-value = 0.0228
therefore,
P( length < 4.98 ) = 0.0228
Hence, out of 1000 chalkboard ordered (0.0228 × 1000) = 23 chalkboard are likely to have lengths of under 4.98 m.
