A manufacturer packs a prize in each box of its cereal and claims that the probabilities of getting various prizes are as follows:

Prize Probability Ring 0.20

Key Chain 0.30

Puzzle 0.15

Pen 0.25

Flashlight 0.10

To see if the companys claim is accurate, a consumer group randomly selects 1,020 boxes of this product and obtains the following data:

Prize Frequency Ring 186

Key Chain 327

Puzzle 168

Pen 225

Flashlight 114

Using a 5% level of significance, test the claim that the distribution of prizes is what the manufacturer claims.
