10.29 The quality control department of a motorcycle company classifies new motorcycles according to the number of defective components per motorcycle at an initial inspection. An improvement to the production process has been implemented, and, hopefully, there will be a change from the historical defective distribution: π": .80, π,-.10, π,-05, π4-03, and π,-.02. A random sample of 300 motorcycles produced under the new system is classified as follows: Number of Defectives Number of Motorcycles, n, 238 32 12 13 0 2 4 or more Total a.05 level, does there appear to be a change in the historical proportions of defectives? Refer to Exercise 10.29. 300 At the 10.30 a. Place 95% confidence intervals on the proportions of the production falling into the five classifications b. Do the confidence intervals support the conclusion reached in Exercise 10.29? c. Why may the conclusion reached using the confidence intervals differ from the conclusion reached in Exercise 10.29?

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.
