2.25. Two types of plastic are suitable for use by an elec- tronic calculator manufacturer. The breaking strength of this plastic is important. It is known that ( σ,-1.0 psi. From random samples of n,-10 and n2= 12 we obtain yi = 162.5 and y2 155.0. The company will not adopt plastic 1 unless its breaking strength exceeds that of plastic 2 by at least 10 psi. Based on the sample information, should they use plastic 1? In answering this...

Q4- Two types of plastic are suitable for use by an electronics component manufacturer. The breaking strength of this plastic is important. It is known that the distribution is normal and a = 02 = 1.0 psi. From a random sample of size n = 10 and n2 = 12, we obtain x1 = 162.5 and X2 = 155. The company will not adopt plastic 1 unless its mean breaking strength exceeds that of plastic 2 by at least 10...

Question 5 1 pts Two types of plastics are suitable for an electronics component manufacturer to use. The breaking strength of this plastic is important. It is known that the standard deviations of the two types of plastics are the same, with a value of 1.0 psi. From a random sample of 10 and 12 for type 1 and type 2 plastics, respectively, we obtain sample means of 162.5 and 155. The company will not adopt plastic 1 unless its...

Question 1 (30 points): Two different types of glass bottles, type 1 and type 2, are suitable for use by a soft-drink beverage bottler. The internal pressure strength of the bottle is an important quality characteristic. From two random samples of the two bottle types of sizes n1 = n2 = 15 bottles, the average pressure strengths of the type 1 and 2 samples are observed to be 183 and 177 psi, respectively, and the standard deviations for the two...
