Refer to Exercise 1.

a. Confirm that the expected counts are large enough to use a chisquare distribution to calculate the P-value. What degrees of freedom should you use?

b. Use Table C to find the P-value. Then use your calculator’s χ² cdf command.

c. What conclusion would you draw about the company’s claimed distribution for its deluxe mixed nuts?

Exercise 1.

A company claims that each batch of its deluxe mixed nuts contains 52% cashews, 27% almonds, 13% macadamia nuts, and 8% Brazil nuts. To test this claim, a qualitycontrol inspector takes a random sample of 150 nuts from the latest batch. The table displays the sample data.
