A chi-square test for homogeneity was conducted to investigate whether the four high schools in a school district have different
absentee rates for each of four grade levels. The chi-square test statistic and p -value of the test were 19.02 and 0.025, respectively. Which of the following is the correct interpretation of the p -value in the context of the test?
Assuming that each high school has the same absentee rate for each grade level, there is a 2.5 percent chance of finding a test statistic 19.02 or larger
Option B. Assuming that each high school has the same absentee rate for each grade level, there is a 2.5 percent chance of finding a test statistic 19.02 or larger
Step-by-step explanation:
Since p value is probability of getting the sample statistic as or more extreme given null hypothesis is true
