Two new machines for producing tires have been proposed by a worker in a manufacture. The manufacture believes there will be no difference in the strength of tires produced by these machines. To test this hypothesis, a sample of 9 tires produced by machine 1 and 7 tires produced by machine 2 were randomly selected. It is known from previous experience that the strength of a tire produced using machine 1 is a normal random variable with standard deviation equals to 3. And the strength of a tire produced using machine 2 is also a normal random variable with standard deviation equals to 4. use the following :information to answer the following questions Machine 2 Machine 1 6.2 4.0 4.1 3.5 3.2 2.8 3.2 5.2 1.5 4.0 6.0 1.0 4.0 5.7 3.8 4.0 [X-X,] Find the estimated difference mean strength of tires produced using both machines 0.06 None of these 0.25- 2,070 2.18-O

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 = 290 and s₁ = 12, and another random sample of 16 gears from the second supplier results in ₂ = 321 and s₂ = 22. Is there evidence to support the claim that supplier 2 provides gears with higher mean impact strength?

Calculate the mean and variance of a negative binomial random variable with parameters p=1/3 and i=25.
Let a be a random variable representing the percentage of protein content for early bloom alfalfa hay. The average percentage protein content of such early bloom alfalfa should be u = 17.2%. A farmer's co-op is thinking of buying a large amount of baled hay but suspects that the hay is from a later summer cutting with lower protein content. A small amount of hay was removed from each bale of a random sample of 50 bales. The average protein content from the samples was determined by a local agricultural college to be -15.8% with a sample standard deviation of S = 5.3%- At a = .05, does this hay have lower average protein content than the early bloom alfalfa?
You own a company called Company X, which has monthly sales that are independent normal random variables with mean 100 and variance 10. Your rival company, called Company Y, has monthly sales that are independent normal random variables with mean 110 and variance 20. (a) Find the probability that your company, Company X, makes more than $307 this quarter (a quarter is 3 months). (b) What is the probability that your company makes more money than your rival company this month?
A computer repair shop has two work centers. The first center examines the computer to see what is wrong and the second center repairs the computer. Let and be random variables representing the lengths of time in minutes to examine a computer () and to repair a computer (). Assume and are independent random variables. Long-term history has shown the following mean and standard deviation for the two work centers: Examine computer, : = 27.3 minutes; = 7.5 minutes Repair computer, : = 90.1 minutes; = 15.3 minutes Let be a random variable representing the total time to examine and repair the computer. Suppose it costs $1.80 per minute to examine the computer and $2.83 per minute to repair the computer. Then is a random variable representing the service charges (without parts). Compute the mean and standard deviation of V. Round your answer to the nearest tenth.
A company produces bags of refined sugar. We are interested in testing the hypothesis that the average weight of the bags is 20 kg. The weights of the contents of these bags are normally distributed with a population variance of 1.96 square kg. The contents of a random sample of 49 bags had a mean weight of 19.7 kg. Then the value of the test statistic is اختر أحد الخيارات a. -1.50 b. 1.50 O C. 1.07 O d. -1.07 O

One of the two fire stations in a certain town responds to calls in the northern half of the town, and the other fire station responds to calls in the southern half of the town. The following is a list of response times (in minutes) for both of the fire stations (this data will be used for several problems). Both samples may be regarded as simple random samples from approximately normal populations so that the t- procedures are safe to use.

Female undergraduates in randomized groups of 15 took part in a self-esteem study. The study measured an index of self-esteem from the point of view of competence, social acceptance, and physical attractiveness. Let x1, x2, and x3 be random variables representing the measure of self-esteem through x1 (competence), x2 (social acceptance), and x3 (attractiveness). Higher index values mean a more positive influence on self- esteem. Variable Sample Mean Standard Deviation Population Size Мean 15 19.48 2.92 X1 X2 X3 (a) Find a 90% confidence interval for u1 - 42.

A company that manufactures aerospace parts is considering the possibility of investing in CMU (Cellular Manufacturing Unit). Top Management desires a good estimates distribution characteristic for the FW. There are three random variables i.e., they have uncertainties in their values. An economic analyst is hired to estimate the desired parameters and FW. He concludes that the scenario presented to him is suitable for Monto Carlo simulation because there are uncertainties in three variables and the direct analytical approach is impossible. The company has done a preliminary economic analysis of the situation and provided the analyst with the following estimates: Capital Investment Normally distributed with mean of $150,000 and standard deviation of $12,000 Useful Life Uniformly distributed with a minimum of 5 years and maximum 10 years Market value $25,000 (single outcome) Annual net cash flow $15,000 probability 0.9 $20,000 probability 0.5 $25,000 probability…
