A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

1. The average cost of rent for a one-bedroom apartment in New York, NY is $2856 per month with
a standard deviation of $233. Assume that the data is bell-shaped symmetric. Use the
Empirical Rule to find each of the following. (Do not use z-scores!!!!!)
a) Find the proportion of people in New York, NY who pay between $2157 and $3089 per month to
rent a one-bedroom apartment.
b) Find the probability that people in New York, NY who pay no more than $3322 per month to rent
a one-bedroom apartment.
c) Find the proportion of people in New York, NY who pay more than $2623 per month to rent a one-
bedroom apartment.
d) Between which two values does the middle 95% of the data lie?
e) Between which two values does the middle 68% of the data lie?
f) Using only the Empirical Rule, explain why it is not possible to find the proportion of people in New
York, NY who pay at least $2500 per month to rent a one-bedroom apartment.

Q. 2. Suppose Country B's government now reports that its population mean disposable household income is $1,000 per month, with a standard deviation of $150. Country A's population mean is $1,100, with a standard deviation of $310. a. b. Which country has more variation in income? Explain using popular phrases, such as "gap between rich and poor." Each country defines the poverty level to be $755. If you assume that income has a normal distribution, find the probability that a household's income is below the poverty level in i. Country A ii. Country B Does it seem reasonable to assume a normal distribution? In general, is income symmetric or skewed?

Atlantic Video is planning to add the new Marvel movie to their collection, and they predict that this will double their demand (i.e. new arrival rate is 60 customers every hour) and halve the standard deviation of the inter-arrival times.
