A recent census revealed that the population mean and population standard deviation for rent paid for studio apartments a city was $1,090 and 30, respectively. This census was way too expensive, so the city is now exploring what it could learn from a random sample a) What is the probability that a sample of 500 would produce a sample mean within $1 of the population mean? b) What is the probability that a sample of 5,000 would produce a sample...

A recent study of 28 city residents showed that the mean of the time they had lived at their present address was 9.3 years and the standard deviation was 2 years. Assuming a normal population, find the 90% confidence interval of the true mean. Interpret the interval estimate. A US Travel Data Center survey conducted for Better Homes and Gardens of 1500 adults found that 39% said that they would take more vacations this year than last year. Find the...

The Census Bureau groups data on households into census tracts,
where each census tract has a total population of about 4,000
residents. Census tracts should be divided so that the households
in the census tracts share certain characteristics, such as
economic status. Even though most tracts are around 4,000
residents, there is some variability, which is the focus of this
lab. In practice, census tracts usually have a population between
1,200 and 8,000 people.
