Answer:
Option c. The distributions of weight loss of the two treatments are approximately normally distributed.
Step-by-step explanation:
To increase the confidence level, the results must be able to satisfy the following conditions:
- The sample size is increased. This reduces the margin of the error in the sampling experiment.
- Reduction of the variability. This means that the less the data varies, the more precise the data is.
- Using the one-sided confidence level
- Lowering the confidence level.
All these characteristics can only be satisfied by the normal distribution curve.

Answer:
25
Step-by-step explanation:
50% is half of something. half of 50 is 25.
Also there is another way to do it. 50/100 = 50%.
50/100 x 50 = 2500/100 = 25. or 50/100 = 1/2. 1/2 x 50 = 50/2 = 25.
