The followingdata represents the ages of a household that consists of five people; 39,37,12,7,7. Parents run a descriptive analysis on the ages of the members of their household. answer the following question.
a) do the data represent a population or a sample? why?
given data represent the population
Because
Here clearly say that data is represent the age of household people they can't say that data is represent the selected people
We know The population is the whole set of values, or individuals, you are interested in. The sample is a subset of the population

2) The graph below represents household income for the US population in the year 2005. The average (mean) income was $63,344 and the median income was $46,326. population standard deviation of $27,435. Assume a 112,363,000 households below $250,000 150000 Total 114,384,000 households 94 705 1250,000 a. Explain why the Empirical rule cannot be used for this data. Why would Chebyshev's rule be a good alternative? According to Chebyshev's rule, what income range would have at least the middle 75% of...

Current Population Reports presents data on the ages of married people. Ten married couples are randomly selected and have the ages shown here: Do the data suggest that the mean age of married men is greater than the mean age of married women? Test at 3% level of significance. (You may use R, again, remember to check conditions) (hint: if you look at a problem and are not sure whether you should use paired t-test or 2 sample t-test, you...
