A statement about a population parameter that is subject to verification is a/an:
Probability Density Function |
||
Normal Distribution |
||
Hypothesis |
||
Critical Value |
||
Average Mean |
The p-value in Hypothesis Testing is:
The z-score at which you would reject the null hypothesis. |
||
the mean plus and minus the standard error. |
||
The probability of the sample results if the null hypothesis is true. |
||
The difference between the mean and the z-score. |
||
The z-critical value based on the confidence level desied. |
When testing a for a population mean, one would use Student’s t-distribution if:
The population mean is equal to the sample mean. |
||
The sample standard deviation is not known. |
||
The significance level is less than 0.05 |
||
the significance level is less than 0.05e) the sample size is > 30. |
Failing to reject the null hypothesis gives:
The strongest possible evidence the null hypothesis is true |
||
Proves the null hypothesis is true |
||
Is a weak result meaning we can’t prove the null hypothesis wrong |
||
An incorrect result |
||
Reason to doubt the statistics behind the test |
Inferential Statistics are:
Techniques used to describe the important characteristics of a set of data. |
||
A group of techniques to measure the strength of association between two variables. |
||
The probabilities based on the assumption we know the number of possible outcomes and that each of the outcomes is equally likely. |
||
The occurrence of one event means that none of the other events can occur at the same time. |
||
The methods used to estimate a property of a population based on a sample. |
