Answer:
60x
Step-by-step explanation:
Let b be the number of books in a box. Then we can say that the total number of books is equal to the number of boxes times the number of books per box.
7b=126 divide both sides by 7
b=18
So there are 18 books per box.
Answer:
No, because all the expected frequencies must be higher than 5.
Step-by-step explanation:
The chi-square test might be performed in those situations in which we need to know if a series of observations adjust or not to a theoretical function, such as the normal, Poisson, or binomial.
The chi-square test does not require the number of files to coincide with the number of columns in the table. It does not establish any restriction about the number of modalities per variable. However, the expected frequencies or counts should not be less than five.
In the exposed example, this unique rule is not accomplished, so the chi-square test can not be performed.
