Consider the observed frequency distribution for the following set of random variables:

Random Variable, x              Frequency, f_o

0 ………………………………          23

1 ………………………………          60

2 ………………………………         122

3 ………………………………          83

4 ………………………………          12

Total ……………………………       300

a. Perform a chisquare test using α = 0.05 to determine if the observed frequencies follow the binomial probability distribution when p = 0.50 and n = 4.

b. Determine the p_value using Excel and interpret its meaning.
