Two suppliers manufacture a plastic gear used in a laser printer. The impact strength of these gears, measured in foot-pounds, is an important characteristic. A random sample of 10 gears from supplier 1 results in 1 = 289.30 and 51 = 22.5, and another random sample of 16 gears from the second supplier results in...

6) Two Suppliers produce the exact component for a particular Customer. Random samples were drawn from the last lot sent in by each Supplier to see if they had any significant difference. Supplier “A” had a mean of 1.607” with a standard deviation of .0020 from a sample of 10 parts. Supplier “B” had a mean of 1.606” with a standard deviation equal to .0018 from a sample of 10 parts. The Customer target value is 1.606”. Supplier “B” charges...

Two suppliers manufacture a plastic gear used in a laser printer. The impact strength of these gears measured in foot-pounds is an important characteristic. A random sample of 10 gears from supplier 1 results in j = 289.30 and si = 22.2, and another random sample of 16 gears from the second supplier results...

To compare the strength of two alloys, 10 independent random samples of each of the alloys were collected. Alloy A had a mean strength of 28,600 kN/m2 with a standard deviation of 6100 kN/m2, while Alloy B had a mean strength of 34,400 kN/m2 with a standard deviation of 5400 kN/m2. Assume the strengths of both alloys are normally distributed. Using a 10% significance level, determine if Alloy B is significantly stronger than Alloy A on average. You are not...
