Please explain what "percentage difference" and "relative standard error" values show in regard the collected data in lab? If they are equal, or if one value is higher than the other, what that means? (percentage difference is the difference divide by average times 100 and relative standard error is standard error divide by mean times 100.) Thanks.

Please explain what I should understand by comparing "percentage difference" with "relative standard error" values together? When is it a good sign, or when is it a bad sign for my collected data? (I know that percentage difference and relative standard error are not the same as percent errors, so please do not involve percent error in your explanation.) Thanks for your help.

Bank of America's Consumer Spending Survey collected data on annual credit card charges in seven different categories of expenditures: transportation, groceries, dining out, household expenses, home furnishings, apparel, and entertainment (U.S. Airways Attache, December 2003). Using data from a sample of 42 credit card accounts, assume that each account was used to identify the annual credit card charges for groceries (population 1) and the annual credit card charges for dining out (population...

1. . The lifetimes of light bulbs produced by a particular manufacturer have mean 1,200 hours and standard deviation 400 hours, The population distribution is normal. Suppose that you purchase 16 bulbs, which can be regarded as a random sample from the' manufacturer's output. a)What is the mean of the sample mean lifetime? Explain. bWhat is the standard error of the sample mean? Explain. c)What is the probability that, on average, these 16...

The SAT scores of 100 students have a mean of 975 and a standard deviation of 105. The GPAs of the same 100 students have a mean of 3.16 and a standard deviation of 0.22. Is the relative variation in SAT scores larger or smaller than that in GPAs? The relative variation in SAT scores is than that in GPAS.
