Pagels is a mammalogist who studies meadow and common voles He frequently traps the moles and has noticed what appears to be a preference for a peanut bufter catmeal mdure by the meado les vs apple slices are usually used in traps, where the common voles seem to prefer the apple slices. So he conducted a study where he used a peanut butler oatmeal miture in hal he rmal apple sices in his remaining traps to see if there was a food preference between the two different voles is null hypothesis is There is no difference between me adow and common is alternate hypothesis is voles

Explanation / Answer

Equality sign should be in the null hypotheis and inequality sign should be in the alternate hypothesis.

Assuming that the peanut mixture is used in half and apple slices in other half. Let us say the peanut mixture and apple slices are divided equally in meadow and common voles.

We can test for mean peanut mixture of meadows (mbar) versus mean peanut mixture of common (cbar)

Null hypothesis, H0:

There is no difference between meadow and common voles

mbar = cbar

Alternate hypothesis, H1:

There is difference between meadow and common voles.

mbar != cbar
