The table shows the monthly subscription price (USD), catalog size (titles), maximum simultaneous streams, whether 4K is included, and whether offline downloads are available for ten fictional streaming platforms.
| Platform | Monthly fee (USD) | Catalog size (titles) | Max streams | 4K included? | Offline downloads? |
| BingeBox | 23.99 | 6200 | 5 | yes | yes |
| CineHaven | 14.49 | 6000 | 3 | yes | yes |
| EchoStream | 8.99 | 4100 | 1 | no | no |
| LumiPlus | 18.99 | 6800 | 4 | yes | yes |
| NovaFlix | 16.99 | 7300 | 4 | yes | yes |
| OrbitPlay | 10.99 | 4800 | 2 | no | yes |
| PixelPrime | 21.99 | 7600 | 4 | yes | yes |

For each of the following statements, select
Yes if the statement is true based on the information presented in the table. Otherwise, select
No.
• Monthly fee and maximum simultaneous streams are positively correlated. A positive correlation means that as one variable increases, the other tends to increase as well. When sorting the table by monthly fee, we can see that the maximum simultaneous streams also tend to increase from the lowest to the highest. This consistent upward trend indicates a positive correlation.
Answer:
Yes • The mode of the maximum simultaneous streams is greater than the range of the maximum simultaneous streams. The mode of a set is the value that appears most frequently, and the range is the maximum value minus the minimum value. The stream counts are 1, 1, 2, 2, 3, 3, 4, 4, 4, 5. The mode is 4, since it appears three times. The range is 5 − 1 = 4. Because the mode equals the range, not greater, the statement is false.
Answer:
No • All platforms with offline downloads but without 4K included have max streams less than the median. The median of a set is the middle value when arranged in order. The stream counts are 1, 1, 2, 2, 3, 3, 4, 4, 4, 5, giving a median of (3 + 3)/2 = 3. The platforms with downloads but no 4K are OrbitPlay and VistaPlay, both with 2 streams. Since 2 is less than the median 3, the condition is satisfied.
