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:
<em>y = - 4x + 5 </em>
Step-by-step explanation:
y = mx + b
(0, b) y-intercept
m = 
~~~~~~~~~~
( - 2, 13)
(0, <em>5</em>) <----- y-intercept
(3, - 7)
(4, - 11)
<em>m =</em> 
= <em>- 4</em>
<em>y = - 4x + 5</em>
No correlation is suggested
Answer:
Communicative Property
Step-by-step explanation:
The communicative property is basically just switching numbers around but still leading to the same answer, if you could see, both of the equations lead to the same answer, 49. Here is a chart to help you out.
