Problem 5.70

A company purchases large lots of a certain kind of electronic device. A method is used that rejects a lot if 2 or more defective units are found in a random sample of 100 units. (a) What is the mean number of defective units found in a sample of 100 units if the lot is 1% defective? (b) What is the variance?

Step 1 of 3

QuadraticRelationship - Check the residual plot to determine of the form of model is appropriate QuadraticModel QuadraticModel(2) QuadraticModel NoteExample ConcaveUpward - As price increase the sales volume decrease at a decreasing rate b0= 539242.8 b1= -765344.8 b2= 290156.24 Interpretations b = 539242.8 0 We predicted the sales volume to be 539242.8 when the price of cat food is 0. - This is extrapolation b1= -765344.8 We have no potential interpretation - What if we increase x1 by 1 unit b 2 290156.24 Since b2 is positive, we have a positive concave upward relationship between price and volume of cat food.
