You give her 70 samples selected randomly, half from the name brand and half from the generic brand. The null hypothese is that she is just guessing and should get about half right. Explain what the first kind of error would be in this case (when you reject the null hypothesis when it is actually true).

Explanation / Answer

Solution:- The first kind of error would be saying that your friend can tell the difference between the two kind of peanut butters, when she really cannot.

In statistical hypothesis testing, a type I error is the incorrect rejection of a true null hypothesis (a "false positive").

In this case type I error will occur when his friend was not really capable of telling the difference but by chance he gave the correct answer.
