The answer to your question is C. I hope this has helped
We just have to multiply 20 by 10mm, which is 200mm. 100mm is equal to one centimeter, so the body length of the insect under the microscope is two centimeters.
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.
