Answer:
a) the mean is $53.50
b) it is a statistic
Step-by-step explanation:
mean = ∑fx/∑f
∑f = 20
mean = (sum of the terms) ÷ (number of terms)
mean = (53+49+54+50+21+46+75+45+63+76+61+63+36+34+54+63+37+62+66+62) ÷ 20 = 1070/20
=$53.50
b) it is statistics because it is a random sample of 20 residential customers not the actual population

Hey there!
For the beginning of the problem, I believe you meant to type "2 3/4" instead of "23/4". But to solve this, you can subtract the numbers 2 3/4 and 1/2 . . .
3/4 - 1/2 . . .
3/4 = 3/4
1/2 = 2/4
3 - 2 = 1
The denominator stays the same, so that leads you to the fraction 1/4 . . .
2 + 1/4 = 2 1/4.
2 3/4 - 1/2 = 2 1/4
You need 2 1/4 quarts of more broth to make the soup.
Hope this helps you.
Have a great day!
