Assume that a chi-square test was conducted to test the goodness of fit to a 9:3:3:1 ratio and a chi-square value of 7.8 was obtained. should the hypothesis be accepted or rejected? why?

The hypothesis should be accepted. The reason is given below.

How to solve for the degree of freedom

we have n = 4

4 - 1 = 3

At a df of 3, the Chi2 of 7.8 would lie between p value of 5 percent and 1 percent. Now if p value is higher than 5 percent we have to accept H0.

What is Chi square

This is the goodness of fit test that is useful for the determination of the observed and the expected differences in the data. P value higher than 5 percent would get us to accept the null.
