An agent for a property management company would like to be able to predict the monthly rental cost for apartments based on the size of the apartment as defined by square footage. A sample of the rent of 25 apartments in a college rental neighborhood was selected, and the information collected revealed the following:   Apartment Size (Sq. Ft.) Monthly Rent ($) 1 850 950 2 1,450 1,600 3 1,085 1,200 4 1,232 1,500 5 718 950 6 1,485 1,700 7 1,136 1,650 8 726 935 9 700 875 10 956 1,150 11 1,100 1,400 12 1,285 1,650 13 1,985 2,300 14 1,369 1,800 15 1,175 1,400 16 1,225 1,450 17 1,245 1,100 18 1,259 1,700 19 1,150 1,200 20 896 1,150 21 1,361 1,600 22 1,040 1,650 23 755 1,200 24 1,000 800 25 1,200 1,750 i)  Determine a 95% interval estimate for the average rent of apartments with 1000 square feet.  Determine ŷ1000 and interpret the interval estimate for the average rent completely…this has been done by Minitab, follow the notes. j) Predict the rent of an apartment with 1650 square feet. What is the S.D. of this estimate?  ie: determine ŷ1650 and SE(ŷ1650)…SE is the same here as it was in part b. k) Determine the correlation coefficient ‘r’ and interpret its meaning.

Determine which of the four levels of measurement​ (nominal, ordinal,​ interval, ratio) is most appropriate for the data below.   Brain volumes measured in cubic cm

Please answer all these questions and label, data included: Size($) Rent(sq.feet) 850 1950 1450 2600 1085 2200 1232 2500 718 1950 1485 2700 1136 2650 726 1935 700 1875 956 2150 1100 2400 1285 2650 1985 3300 1369 2800 1175 2400 1225 2450 1245 2100 1259 2700 1150 2200 896 2150 1361 2600 1040 2650 755 2200 1000 1800 1200 2750 A real estate agent wishes to examine the relationship between the selling price of a home (measured in thousands of dollars) and its size (measured in square feet). In particular she wants to assess if the size of the home can accurately predict the house’s selling price. Use the sample data in the RENT spreadsheet to answer the following questions about the relationship. Which characteristic is the dependent variable? Y = Which characteristic is the independent variable? X = Create a scatter plot for the data set. What does this tell you about the relationship between the variables?     4. What are the…

From the following box plot we can say that: Select one: to. the variable is skewed to the right b. the variable is skewed to the left c. mean and median are equal d. there are no atipical values
