Answer:
The sum of the probabilities is greater than 100%; and the distribution is too uniform to be a normal distribution.
Step-by-step explanation:
The sum of the probabilities of a distribution should be 100%. When you add the probabilities of this distribution together, you have
22+24+21+26+28 = 46+21+26+28 = 67+26+28 = 93+28 = 121
This is more than 100%, which is a flaw with the results.
A normal distribution is a bell-shaped distribution. Graphing the probabilities for this distribution, we would have a bar up to 22; a bar to 24; a bar to 21; a bar to 26; and bar to 28.
The bars would not create a bell-shaped curve; thus this is not a normal distribution.

Step-by-step explanation:
Isolate y in the first inequality:
Now, with both x and y inequalities found, graph it.
12 + 26 + 125 = 163
163 + 0.056(163) = 163 + 9.13 = 172.13
Y=300+40g
Y=5000
5000=300+40g
-300
4700=40g/40
117.5=g
