Answer:

The following hypotheses is a null hypothesis:

There is no difference in the monthly grocery bills of families with one child and families with two children.

Step-by-step explanation:

In inferential statistics, it is a null hypothesis because it is assuming to be true until evidence indicates otherwise, it is a general position without relationship between the two measured phenomena (one child and two children), testing (accepting, approving, rejecting, or disproving), concluding that  there are not reasons for believing that there is a relationship between two phenomena  and gives precise criteria for rejecting the null hypothesis within a confidence level.

Find the mean of the list of data.<br> 49, 65, 41, 38, 87, 55, 95, 106<br> I can’t find the answer
KatRina [158]

Answer:

67.

Step-by-step explanation:

First we find the mean:

Mean is add up everything and divide by how much numbers there are.

The numbers are:

49, 65, 41, 38, 87, 55, 95, 106.

So we add them up which is 536.

Then we divide by how much numbers there are.

There are 8 numbers so 536/8 which is 67.

Hope this helps :D
