Random sample of 250 UCLA students were chosen to study the relationship between the amount of caffeine a student drinks and the grade a student earns in English 100. That is, we want to know if the grade earned in english 100 is independent of the amount of caffeine that a student drinks. passing: 0cups 79, failing 0cups 25
passing 1-2cups 84, failing 28,
passing 3ormore cups 30, failing 4

a)What is the expected value for a student who drinks 1-2 cups/day and passes the class?
b)Using a 1% level of significance and the p-value, what should be the decision regarding the null hypothesis?
c)test statistic
