Linda is carrying 40 grams of seeds. She puts these seeds, in equal amounts, into 4 bags.
What is the mass of seeds in each bag?

10 grams

Step-by-step explanation: 40 grams÷ 10 bags = 4 grams per bag

Option b.

Step-by-step explanation:

Given that a repeated-measures experiment and a matched-subjects experiment each produce a t statistic with df = 10

A matched pair hypothesis test is conducted for the difference in the means for the pairs.

If 11 pairs i.e. 22 entries are compared thenwe have degrees of freedom = 11-1 =10

b. 11 for repeated and 22 for matched

is right answer.

Note: The degrees of freedom (DF) is:

DF = n - 1  

where n is the number of paired observations.
