    A random sample of 400 bolts from machine A contained 36 defective bolts, while an independently chosen, random sample of 325 bolts from machine 8 contained 26 defective bolts. Let p1 be the proportion of the population of all bolt from machine A that are defective, and let p2 be the proportion of the population of all bolts from machine B that are defective. Find a 95% confidenceinterval for Pi-P2. Then complete the table below. Carry your intermediate computations to...

    The percent defective for parts produced by a manufacturing process is targeted at 4%. The process is monitored daily by taking samples of sizes n = 160 units. Suppose that today’s sample contains 14 defectives. Determine a 88% confidence interval for the proportion defective for the process today. Place your LOWER limit, rounded to 3 decimal places, in the first blank. For example, 0.123 would be a legitimate answer. Place your UPPER limit, rounded to 3 decimal places, in the...

    QUESTION 5 The manufacturers of Good-o use two different types of machines to fill their 25 kg packs of dried dog food. On the basis of random samples of size 15 and 18 from output from machines 1 and 2 respectively, the mean and standard deviation of the weight of the packs of dog food produced were found to be 28.332 kg and 0.172 kg for machine 1 and 22.28 kg and 0.245 kg for machine 2. Hence, under the...

    The manufacturers of Good-O use two different types of machines to fill their 25 kg packs of dried dog food. On the basis of random samples of size 15 and 18 from output from machines 1 and 2 respectively, the mean and standard deviation of the weight of the packs of dog food produced were found to be 29.164 kg and 0.382 kg for machine 1 and 24.9 kg and 0.187 kg for machine 2. Hence, under the usual assumptions,...

    Two different types of injection-moulding machines are used to form plastic parts. A part is considered defective if it has excessive shrinkage or is discolored. Two random samples, each of size 300, are selected, and 20 defective parts are found in the sample from machine 1, and 8 defective parts are found in the sample from machine 2. Construct a 99% lower bound on the difference in the two fractions (p1-p2).  Please report your answer to 3 decimals.
