Question

A cereal manufacturer claims that there are an average of 200 raisins in each box of cereal. let µ represent the average number of raisins per box of cereal. you want to test this claim. what is the null hypothesis, , for this situation?

Answer 1

A null hypothesis is a type of hypothesis used in statistics that proposes that no statistical significance exists in a set of given observations.  The null hypothesis attempts to show that no variation exists between variables or that a single variable is no different than its mean. It is presumed to be true until statistical evidence nullifies it for an alternative hypothesis.

So, for the given question Null hypothesis will be

"there are not 200 raisins on average present in the box."

Answer 2

The null hypothesis is that there is not an average of 200 raisins per box.
