Answer:
a.) False
b.) True
c.) True
d.) False
Step-by-step explanation:
a.) This choice is false because you can't know for sure what will happen in the future. The statement uses the word "will" which suggests that you know for sure what will occur. However, the statement also says "tomorrow" and since no one can tell the future, this statement is false.
b.) This statement is true. Let's set up a ratio to solve this problem.
People who payed using cash : Customers
20 : 80
The statement asks about 40 customers, so we need to divide both sides by 2 in order to make the information relevant.
20 : 80
/2 /2
10 : 40
This ratio shows that 10 people would most likely pay with cash in a group of 40 customers. Therefore, the statement is accurate.
c.) The third statement is true. Let's set up a ratio to solve this problem.
People who payed using a credit card : Customers
24 : 80
To put this information in decimal form, divide 24 by 80.
24/80 = .3
Therefore, .3 customers would probably pay using a credit credit card.
d.) The more participants in a survey, the more accurate the results. Therefore, this statement is false because it states the exact opposite of the truth.
Answer:
The statistical test to be used is the paired t-test.
Step-by-step explanation:
The dependent t-test (also known as the paired t-test or paired-samples t-test) compares the two means associated groups to conclude if there is a statistically significant difference between these two means.
We use the paired t-test if we have two measurements on the same item, person or thing. We should also use this test if we have two items that are being measured with a unique condition.
For instance, an experimenter tests the effect of a medicine on a group of patients before and after giving the doses.
Similarly, in this case a paired t-test would be used to deter whether there was any changes in the cholesterol level within each group as result of the treatment.
Thus, the statistical test to be used is the paired t-test.
Answer:
B
Step-by-step explanation:
It will have a closed circle at x = -9 because the inequality means 'greater OR equal to' and it will be shaded to the right.
The standard equation of a circle:
(h, k) - center
r - radius
We have:
<h3>Answer:</h3><h3>The radius of the circle is 4.</h3><h3>The center of the circle is (0, 10)</h3>
