1/14
Determine the constant of proportionality for the table. Express your answer as y = kx
y = 1/2x
x = 1/2y
y = 2x
k = x
Select ALL equations that are proportional.
y = 3x
y = 25x
y = 7x
y = 2x - 1
y = 4000x
Does this equation represent a proportional relationship?
y = 2 + 7x
Yes, because it has a constant of proportionality
Yes, because it will be a straight line
No, because it will not be a straight line
No, because it will not go through the origin

A researcher asked five of his doctor friends if they thought the new Brand X medicine that he developed was effective. Four responded "yes." The researcher used the results to write a TV advertisement claiming that "4 out of 5 doctors prefer Brand X medicine." Is this a valid inference? Explain.
No, because the doctors asked are not a representative sample of the population of doctors.
No, because 4 doctors said yes out of 9 who were asked.
Yes, because the doctors asked are a representative sample of the population of doctors.
Yes, because 4 doctors said yes out of the 5 who were asked.

Shantel and Syrus are researching what types of novels people prefer. They decide to survey people at the mall. Shantel uses systematic sampling and asks every seventh person at the entrance. She finds that 21% prefer romance novels. Syrus uses convenience sampling and asks every person in only one store. He finds that 48% prefer romance novels. Whose inference do you agree with?

A representative sample of 80 customers in a clothing store was surveyed about how they paid for their purchases. The table shows the responses. Based on the results, which of the following are valid inferences. Select all that apply.
Tomorrow, 8 out of the first 80 customers will for sure pay with a gift card.
In a group of 40 customers, it is expected that about 10 will pay with cash.
About 0.3, or 30%, of all the store's customers will pay with a credit card.
A sample of 100 customers would provide less reliable data.
