The lecture Comparing two Means by David Spade, PhD is from the course Statistics Part 2. It contains the following chapters:
Before carrying out any inference for the difference between two means, what is the first thing that should be done?
Which of the following is not a condition for the use of the twosample tinterval?
When is the pooled ttest appropriate?
Which of the following is true regarding the differences between the twosample tprocedures and the pooled tprocedures?
Which of the following is true of twosample inference?
What is the tstatistic if hypothesized mean difference is 3, sample mean difference is 1, sample standard deviation of the difference is 2, and sample size is 25?
For which of the following hypothesis are we likely to use a twotailed test?
Zdistribution is used when population standard deviation is known and the sample size is greater than what value?
