A SYMMETRIC distribution with ONE parameter used when the population standard deviation is unknown - (9) degrees of freedom
A NORMAL distribution with mean 0 and standard deviation 1 - (3) Standard Normal Distribution
The distribution of a sample statistic - (14) Sampling Distribution
Gives the NORMALITY of sample means for large sample - (2) Central Limit Theorem
Using data to determine properties of population parameters - (11) Inference
A single value used to estimate a population parameter - (13) Point Estimate
A z-score determined by the probability (1-Confidence Level/100)/2 - (8) Critical Value
t-distribution PARAMETER equal to n-1, where n the the sample size used to estimate the sample mean and standard deviation - (10) Student's t Distribution
An INTERVAL with known likelihood of containing the population parameter - (6) Confidence Interval
A known percentage SUCCESS RATE in which a confidence interval will contain the unknown population parameter - (7) Confidence Level
One-Half the WIDTH of a confidence interval - (1) Margin of Error
Gives the number of STANDARD DEVIATIONS a value is from the mean - (4) Z- score
Standard deviation of a sample statistic - (12) Standard Error
Using a large sample size n>30, the average of sample means approaches this value - (15) Population Mean
