A company makes cartons finds the probability of producing a carton with a puncture is 0.03, the probability that a carton has a smashed corneris 0.06, and the probability that a carton has a puncture and a smashed corner is .002. If a quality control inspector selects a carton find the probability that the carton has a puncture or has a smashed corner
Festival Histogram: Beginning with in the text on spotting outliers, correct the type in the data as directed - create a separate histogram for each day, Day1, Day2, and Day3, using the hygiene variable for all three days. Include the normal curve
In a 2^6 factorial form a 4 blocks with eight treatment combination. Confirm higher order interaction and any other two in such a way that generalized interaction is not violated and also 2 factor interaction and main treatment is not confounded.
Why does a p-value provide a true measure of statistical significance? Try to relate your answer to previously covered concepts - example continuous probability distributions.
The average weekly earnings of the plumbers in a city is [Mu=$750] with a standard deviation of [s=$40]. Assume that we select a random sample of [n=64 plumbers], what is the probability that the sample mean [x] will be greater than $740 or greater ..
1. Determine the critical value for a left-tailed test of a population mean at the α=0.005 level of significance based on a sample size of n = 30. A) 2.750 B) 2.756 C) -1.699 D) -2.756 E) None of these 2. If beta is computed to be 0.763 , then the p..
