<h3>Explain how Rashad could collect data to ensure that it is a random sample of the population.</h3>For Rashad's sample to be a random sample gotten from the population, the following must be considered.
- First, he must have a defined population. In this case, his population is all the students in his high school (non students are not to be considered)
- Next, he must have a defined sample size (say 10% or 20% of the total number of students in the school)
- Next, he must select students at random (a perfect example of this is one of every five or ten students that enters the school gate.
- Lastly, he must collect data for his sample
To do this, we simply create a bar graph.
The response would go into the x-axis, while the number of people would go into the y-axis
See attachment for bar graph
<h3>What is the average view of the dress code? How did you come to this conclusion?</h3>The average view of the dress code is that this dress is not good
It is considered the average view of the dress code because it is the opinion with the most frequency
<h3>Will the dress change?</h3>The number of students that do not like the dress as:
210 + 206 + 770 = 1186
Their percentage is
Percentage = 1186/(210 + 206 + 770 + 358)
Percentage = 77%
This means that
Yes, the dress will change
