The lecture Comparing two Means by David Spade, PhD is from the course Statistics Part 2. It contains the following chapters:
What should be performed before carrying out any inference about the difference between two means?
What is not a condition necessary for a twosample tinterval?
When is the pooled ttest appropriate?
What is true regarding the differences between the twosample tprocedures and the pooled tprocedures?
What is true of twosample inference?
For which hypothesis are we likely to use a twotailed test?
A zdistribution is used when the population standard deviation is known and the sample size is greater than what value?
