How is the test statistic for a claim about 2 population means, independent samples, standard deviations unknown, similar to the test statistic for 1 population mean, standard deviation unknown?
1) Stocks A, B, C and D have standard deviations, respectively, of 20%, 5%, 10% and 15%. Which one is the riskiest? a) Stock A b) Stock B c) Stock C d) Stock D 2) Find the standard deviation for a security that has 3 one-year returns of -5%, 15% and 20%. a) 6.25% b) 13.23% c) 11.41% d) 5%
(4 pts, 2 pts each) The following are the means and standard deviations of some well-known standardized tests, referred to as Test A, Test B, and Test C. All three yield normal distributions. Test Mean Standard Deviation Test A 500 100 Test B 150 8 Test C 70 15 a. (2 pts) A score of 450 on Test A corresponds to what score on Test B? b. (2 pts) A score of 625 on Test A corresponds to what score...
3) If a process has a Cpk of 1.33, How many Standard Deviations would that cover? If the process produced 100,000 parts, how many non-conforming parts would you expect to produce? Would you feel the need to 100% Inspect?
How many standard deviations away from the mean (mean=7.96, standard deviation = 0.89) is 6.5 if the data follows a normal distribution?
Assuming that the population (or sample) has a normal distribution, how many standard deviations above and below the mean contains 99% of the population (or sample)?
approximately 95% of all values of a normally distributed population lie within how many standard deviations of the population mean
