Answer:
2
Step-by-step explanation:
The mode is the value that appears the most times in the data. In other words, it has the largest frequency.in some questions this is denoted as MO
Here, each number appears,
1 appears 2 times
2 appears 3 times
3 appears once
6 appears once
7 appears once
So, it is clear that 2 appears the most number of times.

Answer:
The probability is ![P(X > 20 ) = 0.8](https://tex.z-dn.net/?f=P%28X%20%3E%2020%20%29%20%3D%20%200.8)
Step-by-step explanation:
From the question we are told that
The closing price of Schnur Sporting Goods Inc. common stock is uniformly distributed between $18 and $28 per share.
Given that the stock is uniformly distributed then the probability that the stock price will be more than $20 is mathematically evaluated as
![P(X > 20 ) = 1 - P(X < 20 )](https://tex.z-dn.net/?f=P%28X%20%3E%2020%20%29%20%3D%20%201%20-%20P%28X%20%3C%2020%20%20%29)
Since it is uniformly distribute between $18 and $28 per share then we can solve is as follows
=> ![P(X > 20 ) = 1 - [\frac{ 20 - 18 }{28 -18} ]](https://tex.z-dn.net/?f=P%28X%20%3E%2020%20%29%20%3D%20%201%20-%20%5B%5Cfrac%7B%2020%20-%20%2018%20%7D%7B28%20-18%7D%20%5D)
=> ![P(X > 20 ) = 0.8](https://tex.z-dn.net/?f=P%28X%20%3E%2020%20%29%20%3D%20%200.8)
