Step 1
Step 1: Define the factors and levels In this experiment, we have two factors: - Factor A: Thread type (5 levels: Thread 1, Thread 2, Thread 3, Thread 4, Thread 5) - Factor B: Measuring instrument (4 levels: I1, I2, I3, I4) Show more…

42.6. A laboratory technician measures the breaking strength of each of 5 kinds of linen thread by means of 4 different instruments and obtains the following results (in ounces): Measuring instrument Thread 1 Thread 2 Thread 3 Thread 4 Thread 5 24 24.5 21.5 Looking upon the threads as treatments and the instruments as blocks, perform an analysis of variance at the level of significance α = 0.01.

The director of manufacturing at a clothing factory needs to determine whether a new machine is producing a particular type of clothing according to manufacturer’s specifications, which indicate that the clot should have a mean breaking strength of 32kg and standard deviation of 2.72 kg. A sample of 49 pieces of cloth reveals a sample mean breaking strength of 31.3kg. i) Compute the 99% confidence interval and explain its meaning (4 marks) ii) Is there evidence that the machine is not meeting the manufacturer’s specifications for average breaking strength? Use a 5% level of significance. (6 marks)

13.1 Six different machines are being considered for use in manufacturing rubber seals. The machines are being compared with respect to tensile strength of the product. A random sample of four seals from each machine is used to determine whether the mean tensile strength varies from machine to machine. The following are the tensile-strength measurements in kilograms per square centimeter × 10⁻¹: Machine 1 2 3 4 5 6 17.5 16.4 20.3 14.6 17.5 18.3 16.9 19.2 15.7 16.7 19.2 16.2 15.8 17.7 17.8 20.8 16.5 17.5 18.6 15.4 18.9 18.9 20.5 20.1 Perform the analysis of variance at the 0.05 level of significance and indicate whether or not the mean tensile strengths differ significantly for the six machines.
