A national youth organization sells six different kinds of
cookies during its annual cookie campaign. A local leader is
curious about whether national sales of the six kinds of cookies
are uniformly distributed. He randomly selects the amounts of each
kind of cookies sold by five youths and combines them into the
observed data that follow. Use α = .05 to determine whether the
data indicate that sales for these six kinds of cookies are
uniformly distributed.
Kind of Cookie | Observed Frequency |
Chocolate chip | 183 |
Peanut butter | 168 |
Cheese cracker | 155 |
Lemon flavored | 161 |
Chocolate mint | 216 |
Vanilla filled | 165 |
