A company says its premium mixture of nuts contains 10% Brazil nuts, 20% cashews, 20% almonds, 10% hazelnuts, and the rest are peanuts. You buy a can of nuts and separate the various kinds of nuts. Upon weighing the nuts, you find there are 112 grams of Brazil nuts, 183 grams of cashews, 207 grams of almonds, 71 grams of hazelnuts, and 446 grams of peanuts. You wonder whether your mix is significantly different from what the company advertises.

What are the X^2 and p-value for the test?

X^2 = 12.7 p = .098

X^2 = 15.5 p = .047

X^2 = 16.2 p = .030

X^2 = 1
