FAQs on the exercise One Sample T-Test II
- In this exercise, we expect the population mean to be 30 but the mean of our sample is 31. So wouldn’t our null hypothesis be: the sample represents a population of mean 31?
We then go on and use
test_1samp(ages, 30)to find the p-value. I am unclear about these steps.
What are we checking for in this hypothesis test? Are we checking If the sample represents a population of mean 30? If so, if it is less than 0.05 then does it mean it represents a population of mean 30?
