Continuous Random Variable

Question 1

Properties of Continuous Uniform Distribution

Answer 1

Shape = rectangle

Total area = 1

X - R [a,b]

Question 2

How do you work out the mean of continuous uniform distribution

Answer 2

If X-R [a,b]

Mean = a+b/2

Because the shape is symmetrical

Question 3

Properties of 2 variable distribution

Answer 3

At each x value, the y variable is normally distributed

x and y generally have a linear relationship

the scatter diagram of x and y shows an oval shape

Question 4

What does n have to be in normal approximation to binomial distribution

Answer 4

Large

Question 5

What does p have to be in normal approximation to binomial distribution

Answer 5

Close enough to 0.5
