What is confidence level?

Probability of 1-alpha.

100

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

100

When do you reject the H0 in critical value method?

If the test statistic is in critical region.

100

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.

200

A research specification that dictates that parties are not made aware of the study, treatment or outcome to be measured.

Blind study

200

H1

Parameter that differs from H0.

200

An aspect of a population

What is parameter?

200
Sampling to to prevent bias, by assessing a treatment group based on the day, week or month in which patients are encountered in a study.
What is alternative time sampling?
300
Rejections of the null hypothesis when the hypothesis was true.
What is type 1 error?
300

What is H0?

Parameter that is being tested.

300

What are the three ways in which we can reject H0?

P-value method

Critical value method

Confidence Interval method

300

q=

1-p

400

How to find population proportion?

x/N (success/population size)

400
An exact statement that the results are a chance of variation (the opposite of the hypothesis).
What is null hypothesis?
400

What will you use to make a conclusion about the problem? (Point at the diagram)

SI will check it

400

Conditions for binomial distribution are:

Two outcomes

Fixed number of trials

Independent

p of success is the same

500
Failure to accept the alternative hypothesis when the alternative hypothesis was true.
What is type II error?
500

How to find confidence interval?

1PropZint

500

How do you define the right tailed test, what do you look at?

H1

500
A large group of people or places or objects that are the main focus of a scientific query.
What is population?
