.5. national manufacturer of ball bearings is experimenting with two different processes for producing precision ball bearings. It is important that the diameters he as close as possible to an industry standard. The output from each process is sampled and the average error from the industry standard is calculated. The results are presented below. WW Mean imm Illlmm Standard Deviation lmm [llme Sample Size 12 14 The researcher is interested in determining whether there is evidence that Process A yields a higher average error than Process 3. Assume that the population standard deviations are equal. This example is what type of test? Select one: Q a. One sample test of means. O b. Two sample test of means. O c. Paired ttest. C) d. Test of proportions. Mean output of solar cells of three types are measured six times under mndom light intensityI over a period of 5 minutes. yielding the results shown below. Heseanch question: is the mean solar cell wtmIt the same for all cell types? This problem involves which of the following tests? 3} Comparing proportions of two or more groups b] Cine Factor ANDWL c) Two Factor ANDUA without Replication cl] Two FectorAND'm with Replication e) None of the Above Mean outpu't ort solar cells erf three types are measured six times under Iandom light intensity over a period of 5 minutes. yielding the results shown below.
