What is confidence level?
Probability of 1-alpha.
The process of choosing the individuals who are easiest to reach or sampling that is easily done; the sample does not represent the entire population.
Convenience type of sampling
When do you reject the H0 in critical value method?
If the test statistic is in critical region.
If H1: p>0.54 will the region be on the left/right/two tailed?
The region that we are looking at will be on the right.
A research specification that dictates that parties are not made aware of the study, treatment or outcome to be measured.
Blind study
H1
Parameter that differs from H0.
An aspect of a population
What is parameter?
What is H0?
Parameter that is being tested.
What are the three ways in which we can reject H0?
P-value method
Critical value method
Confidence Interval method
q=
1-p
How to find population proportion?
x/N (success/population size)
What will you use to make a conclusion about the problem? (Point at the diagram)
SI will check it
Conditions for binomial distribution are:
Two outcomes
Fixed number of trials
Independent
p of success is the same
