Chi square test


#1

ques…There are 60 percent chances of a customer arrival in an 8 hour shift. In a random sample of 250 days
NUMBER of customers in a day 0 1 2 3 4
NUMber of days 18 77 103 52
at 10 percent significance level does data follows binomial distribution.


#2

H0: Data follows a Binomial Process
Ha: Data doesn’t follow a Binomial Process

of customer, frequency ,binomial probability, expected

0 18 0.064 16
1 77 0.288 72
2 103 0.432 108
3 52 0.216 54
sum 250
chi square test probability =0.824757
Since the p value is greater than significance level so the data is following the binomial distribution.
