- Answer the following questions. 3. When given two separate events, how do we know whether to apply the Addition Principle or the Multiplication Principle when calculating possible outcomes? What conjunctions may help to determine which operations to use?a) Interpret the coefficient on pfmeals in Model 2 (mathematically and statistically). b) is the coefficient on pfmeals in Model 1 biased compared to the coefficient on pfmeals in Model 2. If so, by how much? c) What 2 conditions would need to be true for bias of pfmeals to exist? Use only the information from Models 1 and 2 above to answer this question.One sample has n = 8 and SS = 168. A second sample has n = 6 and SS = 126. What is the pooledvariance for these two samples
- A purchaser of alarm clocks buys them in lots of size 10. It is his policy to inspect 3 clocks randomlyfrom a lot and to accept the lot only if all 3 are nondefective. If 30 percent of the lots have 4 defectiveclocks and 70 percent have only 1, what proportion of lots does the purchaser reject?A producer of pocket calculators purchases the main processor chips in lots of1,000. The producer would like to have a 1 percent rate of defectives but willnormally not refuse a lot unless it has 4 percent or more defectives. Samples of50 are drawn from each lot, and the lot is rejected if more than two defectives arefound.a. What are p0, p1, n, and c for this problem?The following are the number of defective bolts produced by two machines. Machine A Machine B 2 3 4 7 6 0 5 2 8 11 10 9 1 7 3 1 6 8 Which machine is showing the more consistent performance?
