j) In the p-value approach, if p-value>a (the level of significance) we reject the null hypothesis. If you fail to reject the null hypothesis at the 5% level, then the probability k) that you are wrong is always 5%. 1) The level of significance is the probability of rejecting the null hypothesis when the null hypothesis is true.

8) Some claim that magnets can be used to reduce pain. Design a double-blind experiment to
test this claim. Write a brief proposal that includes important details including the number
of subjects, how subjects are assigned to groups, and how you will make the study double
blind.

A census gets information from every member of the population.
A sample gets information from a proper subset of the population.
A stratified sample is where you partition the population into two or more groups
