2
Point and Interval Estimation
set limits regarding the containment for the population parameter
have a goal of learning more about the value of a mean or mean difference
3
Multiple Choice
In point and interval estimation, a goal is to make a decision regarding a null hypothesis.
True
False
4
False
The goal is to estimate the value of the population mean, not make a decision about it.
5
Point estimation
uses a sample statistic to estimate a population parameter.
6
Interval estimation (confidence interval)
the interval or range of values within which an unknown population mean is likely to be contained
7
Interval estimate or confidence intervals are reported as a point estimate
± an interval estimate.They are stated with a level of confidence which defines the probability or likliehood a parameter is contained in the interval.
8
To compute and interpret confidence intervals...
Compute the sample mean and standard error
Choose the level of confidence and find the critical values
Compute the estimation formula to find the confidence limits

Fill in the Blanks
What are the upper and lower limits of a 95% confidence level in the estimation formula 12 ± 2.3
Type answer...
11
Multiple Choice
If a sample size is increased the precision of a confidence interval will...
increase
decrease
not change
12
Increasing the sample size increases the precision of the confidence level
The more observations that you have, the narrower the interval around the sample statistic. Often the researcher weighs the benefits of this as increasing sample size may not be practical.
13
Multiple Select
Another way to increase precision in the confidence interval would be...(check all that apply)
reduce variability
use effect testing
lower the confidence level
14
Lowering the confidence level...
The advantage is an increase in precision, but the disadvantage is that you have less confidence that the confidence interval contains the population parameter you are interested in-.
Example - Lowering a 95% CI to 90% CI
15
Multiple Choice
If the null hypothesis is outside of the confidence interval, the researcher should ________ the null hypothesis.
retain
reject
16
Multiple Choice
A researcher compared the time in seconds that children in two classrooms remained seated during a behavioral task. The null is that the two classrooms will not differ. She reports a 95% CI = -2.1 to 32.6 seconds. What would the decision have been for a hypothesis test?
reject the null
retain the null
