Question
40 is selected from a large population with
0. 4. A second random sample of size n2 = 30 is
A random sample of size n1
proportion of successes P1
selected from a different large population with proportion of successes p2 = 0. 6.
Which of the following correctly describes the shape, center, and variability of the
sampling distribution of P1 – P2?
The shape is unknown and Uô,
0. 2
The shape is approximately normal and Uô, - µô, = 0. 2
= 0.
The shape is approximately normal and the mean is unknown
The shape is unknown and lp,
- Hô, = -0. 2
The shape is approximately normal and lp,
– Hô, =
-0. 2
