The next seven questions refer to the following scenario: A random sample of 16 Porsche drivers yielded an average age of 50 years with a variance of 9 years and a random sample of also 16 Ferrari drivers yielded an average of 47 years with a variance of 25 years. Porsche Driver Ferrari Driver n 16 16 mean 50 47 Variance 25 Conduct the following hypothesis test at a=0.05. HO: Mean Age Porsche Drivers Mean Age Ferrari Drivers Assume unequal variance.
Hypothesis Test of the Difference Between Two PAIRED Means. Im pretty sure this should be a one tailed test, as does my teacher does an example for this and her's had one tail. Help me understand which tail it is (what lead you to believe it was right or left tail.) I will need the test statistic and critical value(s). You will need the null and alternative (H0: u1=u2, H1: u1=/=u2). The equation that is needed to solve this is t= d *bar* - Ud / (Sd/*square root* of n) D.O.F formula to be used is n-1. This is all the infomartion I think you need might need to determine the kind of problem this is. I've asked this question before but it seems I didn't provide enough information and the answers included two tailed test or something else. Oh also I need these formulas to be used, as in no excel to speed things up because as much as i like shortcuts I need to understand this concept. Standard dev or Sx should be 1.414213562. Pretty sure this is right, not 100%. d *bar* should = -2, pretty…

A local company makes snack-size bags of potato chips. The company produces batches of 400 snack-size bags using a process designed to fill each bag with an average of 2 ounces of potato chips. However, due to imperfect technology, the actual amount placed in a given bag varies. Assume the population of filling weights is normally distributed with a standard deviation of 0.1 ounce. The company periodically weighs samples of 10 bags to ensure the proper filling process. The last five sample means, in ounces, were 1.99, 2.02, 2.07, 1.96, and 2.01. Is the production process under control? Group of answer choices A. No, because the sample means show a downward trend. B. Yes, because the sample means show a downward trend. C. No, because the sample means fall within the upper and lower control limits. D. Yes, because the sample means fall within the upper and lower control limits.
