- Spacers are manufactured to the mean dimension and tolerance shown in Figure 29-12. An inspector measures 10 spacers and records the following thicknesses: 0.372" 0.376" 0.379" 0.375" 0.370" 0.373" 0.377" 0.378" 0.371" 0.380" Which spacers are defective (above the maximum limit or below the minimum limit)? All dimensions are in inches.At Quickie Car Wash, the wash process is advertised to take less than 7 minutes. Consequently, management has set a target average of 400 seconds for the wash process. Suppose the average range for a sample of 9 cars is 12 seconds. Use the accompanying table to establish control limits for sample means and ranges for the car wash process. The UCLx equals enter your response here seconds and the LCLx equals enter your response here seconds. (Enter your responses rounded to two decimal places.)With α = .01, the two-tailed critical region for a t test using a sample of n = 16 subjects would have boundaries of

- Thomas wants to compare the mean concentration of carbon monoxide (CO) on residential versus commercial streets, since these differ in terms of car traffic. In each of three neighborhoods of Montréal (named A, B, and C below), he randomly chooses four locations for each type of street, for a total of 24 observations (2 street types x 3 neighborhoods x 4 locations). At each location, he measures CO concentration in the air over a period of 10 hours (8:00 AM-6:00 PM), and obtains the following data (in ppm/h). 10-a) Draw a graph that gives insight into the possible presence of an interaction between the two classification factors. Do you suspect the presence of an interaction? Explain why. IMG 4569 10-b)Test whether or not the difference between residential and commercial streets in mean atmospheric CO concentration is the same among the three neighborhoods, and whether or not CO concentration in the air is the same, on average, for the two types of streets.

In each of three neighborhoods of Montréal (named A, B, and C below), he randomly chooses four locations for each type of street, for a total of 24 observations (2 street types x 3 neighborhoods x 4 locations). At each location, he measures CO concentration in the air over a period of 10 hours (8:00 AM-6:00 PM), and obtains the following data (in ppm/h). Question: Test whether or not the difference between residential and commercial streets in mean atmospheric CO concentration is the same among the three neighborhoods, and whether or not CO concentration in the air is the same, on average, for the two types of streets. Note that Neighborhood is considered a random block factor in the ANOVA. Use significant level= 0.05.A manufacturer of computer stands made a batch of 40,000bases. 500 bases were taken to make a measurement of the width of thebase obtaining the following results.-Average: 20.10 cmStd Deviation: 1cmIf the customer's width specification of this base is: from 17.1 cm to22.5cm.For the batch of 40,000 bases,a) How many bases does the lot have below the maximum width?(including those that could be below the lower limit)b) What is the CPK of this process?
