1. Which of the following illustrates a normal curve distribution? 2. Which normal curve has a greater mean? Explain your answer, 3. Which normal curve has a greater standard deviation? Explain your answer. 4. Compare the means of A and C. 5. Compare the standard deviations of A and E​

Sagot :

Possible Answers:

1. A continuous probability distribution is a representation of a variable that can take a continuous range of values.

2. Standard Deviation, Curve A has the greater mean (The line of symmetry of curve A occurs at x = 15.

3. The steeper the bell curve, the smaller the standard deviation. If the examples are spread far apart, the bell curve will be much flatter, meaning the standard deviation is large. In general, about 68% of the area under a normal distribution curve lies within one standard deviation of the mean.

4. (there's no A and C)

5. (there's no A and E)
