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.

# Chi square test

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.
