A team of researchers analyzed the meat from each in a sample of 19 "red snapper" fish fillets purchased from vendors across a region in an effort to estimate the true proportion of fillets that are really red snapper. DNA tests revealed that 16 of the 19 fillets (or 84%) were not red snapper but a cheaper look-alike variety of fish. Complete parts a through c. a. The parameter "x" is the true proportion of fish fillets that are actually red snapper. True False b. Explain why it is not appropriate to use a confidence interval in this study. Choose the correct answer below. O A. It is inappropriate because the sampling distribution is approximately normal. O B. It is inappropriate because either the number of successes in the sample or the number of failures in the sample is less than 5. Oc. It is inappropriate because the expected probability of success is 0.84. O D. It is inappropriate because either the number of successes in the sample or the number of failures in the sample is greater than or equal to 5. c. The population (true) proportion of fish fillets that are actually red snapper is (Use 2 decimal places rounded.)

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
