All things being equal; demand decreases, as price increases.
The quantity supplied when price is $4 is 28
From table 4.4 (see attachment).
When price = $4, we have the following supplies:
- <em>Firm A = 6</em>
- <em>Firm B = 6</em>
- <em>Firm C = 8</em>
- <em>Firm D = 10</em>
<em />
So, the total supply at $4 is:


Hence, the quantity supplied when price is $4 is 28

I believe it is C because I counted the dots in the shaded region.
Hope it is correct :)
Answer:
the answer is below
Step-by-step explanation:
We have the total number of possible samples = 4 * 4 = 16 (As 4 choices for each value)
in addition we have to as all sample occur with equal probability, probability of each sample = 1/16, below is samling distribution of mean
x1 x2 probabilityP(x1,x2) sample mean
190 190 1/16 190
190 100 1/16 145
190 272 1/16 231
190 74 1/16 132
100 190 1/16 145
100 100 1/16 100
100 272 1/16 186
100 74 1/16 87
272 190 1/16 231
272 100 1/16 186
272 272 1/16 272
272 74 1/16 173
74 190 1/16 132
74 100 1/16 87
74 272 1/16 173
74 74 1/16 74
Summarizing above with adding duplicate values
sample mean probability
74 1/16
87 1/8
100 1/16
132 1/8
145 1/8
173 1/8
