The mean weight of trucks traveling on a particular section of I-475 is not known. A state highway inspector needs an estimate of the mean. He selects a random sampleof 49 trucks passing the weighing station and finds the mean is 15.8 tons, with a standard deviation of the sample of 4.2 tons. What is the probabilty that a truckwill weigh less than 14.3 tons?
Using the Empirical Rule, approximately how much probability is less than -1 AND greater than +1 standard deviations from the mean of normal distribution with mean mu & standard deviation sigma?
From a sample of 65 meth addicts, you find that the mean number of tattoos is 17.3, with a sample standard deviation of 6.8. Test the null hypothesis that your sample came from a population whose mean number of tattoos is 15 against the alternative hypothesis that Mu is less than 15. Use alpha = .01. Formally state the null and the alternative hypothesis for this test (3 pts) What is the critical value(s) for this test? (3 pts) Interpret...
