During an experiment, readings for blood pressure in a person’s body were found to be constant. However, when measured by a different blood pressure cuff, the readings differed by 15 points for each reading. This difference indicates that the results are either independent, reliable, valid but not dependent, reliable, valid

Answer:
Valid but not reliable

I just did it lol
Answer:
The differences in the results indicate that the results are independent of each other, and they may or may not be reliable or valid.
Explanation:
If the blood pressure cuff would be the same then we could have concluded that the second reading might be manipulated due to the first reading. But, since the cuffs are different, we can conclude that they are definitely independent in providing the results.
Reliability and validity depend on the accuracy of the device used. If both the cuffs are used properly then the results and differences between them are reliable and valid. But if there are some misleads in the accuracy such as wrong cuff size, wrong positioning of the patients, or wrong cuff placement, then the results are not so reliable.
