The process that makes the spaghetti noodles for Delectable Delights is supposed to produce noodles with an average length of 252 mm.   Allison, the Quality Control Manager, is concerned that Machine #42 is not working properly and the noodles it produces are too short. You are asked to take a random sample of 40 noodles from Machine #42 and perform a hypothesis test to determine if the noodles produced by the machine are, on average, less than 252 mm. Use a significance level of 5%.

  1. Define μ in the context of the problem and state the appropriate hypotheses. (5 pts)

  1. State and verify the conditions for this hypothesis test for a mean. (5 pts)

The mean diameter of a spindle in a small motor is supposed to be 5 mm. If the spindle is either too small or too large, the motor will not perform properly. The manufacturer measures the diameter in a sample of 60 motors to determine whether the mean diameter has moved away from the target. They found the mean diameter of the sample to be 4.951 mm. From past studies it is known that the population standard deviation is 0.2...

A coffee machine is supposed to dispense 12 ounces of coffee in each cup. A business using one of these machines is concerned that it is dispensing less than 12 ounces. An inspector takes a sample of 16 cups of coffee, and finds a mean of ¯x=11.7x¯=11.7 ounces with a standard deviation of s=0.8s=0.8 ounces. (Assume coffee serving volumes are normally distributed.) 1. What are the null and alternate hypotheses for this study? H0: μ (< > ≤ ≥ =...

steel factory produces iron rods that are supposed to be 36 inches long. The machine that makes these rods does not produce each rod exactly 36 inches long. The lengths of these rods vary slightly. It is known that when the machine is working properly, the mean length of the rods is 36 inches. According to design, the standard deviation of the lengths of all rods produced on this machine is always equal to .05 inches. The quality control department...

A city councilwoman is concerned that the new contractor she hired is taking too long to replace defective streetlights. She would like to perform a hypothesis test to determine if the replacement time for streetlights under the new contractor is in fact longer than the replacement time under the previous contractor, which was 3.2 days on average. She selects a random sample of 12 streetlight service calls and obtains the following times to replacement (in days). Use a significance level...

Cough-a-Lot children’s cough syrup is supposed to contain 6 ounces of medicine per bottle. However, since the filling machine is not always precise, there can be variation from bottle to bottle. The amounts in the bottles are normally distributed with σ = 0.3 ounces. A quality assurance inspector measures 10 bottles and finds the following (in ounces): 5.95 6.10 5.98 6.01 6.25 5.85 5.91 6.05 5.88 5.91 Are the results enough evidence to conclude that the bottles are not filled...

The Toylot company makes an electric train with a motor that it claims will draw an average of no more than 0.8 amps under a normal load. A sample of nine motors were tested, and it was found that the mean current was x = 1.30 amps, with a sample standard deviation of s = 0.43 amps. Perform a statistical test of the Toylot claim. (Use a 1% level of significance.) What are we testing in this problem? single proportionsingle...
