Carrying Out a Chi-Square Test for Goodness of Fit

AP Statistics· difficulty 2/5

A chi-square goodness-of-fit on a six-category variable returns chi-square = 11.2 and p = 0.048.

At alpha = 0.05, what conclusion?

A
$Reject H0; data inconsistent with claimed distribution$

B
$Fail to reject H0$
C
$Reject H0; data fit the distribution$
D
$Accept H0$

Explanation

Since p = 0.048 < 0.05, reject H0. There is evidence the observed counts are inconsistent with the hypothesized distribution.
