2
Q
When tabulating probabilities, in your calculator you must use….
A
Binomial CD
3
Q
If the probability is 0.5…
A
The graph will be symmetrical and therefore have no skew
4
Q
A positive skew is seen in a distribution if…
A
The values start decreasing as x increases
5
Q
P(X > x) = …
A
1 - p( x < x-1)
6
Q
If the answer in your hypothesis test is lower than the significance level then…
A
The null hypothesis is rejected
7
Q
If the answer in your hypothesis test is greater than the significance level then…
A
The null hypothesis is not rejected
8
Q
The critical region is…
A
The point in the binomial distribution where it is lower than the significance level and moving 1 value further would make it greater.
