Answer:

Not independent

Step-by-step explanation:

The number of single bedroom apartments is 90;

The number of single occupants in that 90 is 64;

64/90 or 32/45 is the rate that a single occupant lives in a 1 bedroom apartment.

The number of multiple bedroom apartments is 110;

The number of single occupants in that 110 is 12;

12/110 or 6/55 is the rate that a single occupant lives in a multiple-bedroom apartment.

The rate of single occupants in any type of apartment is 76/200 or 19/50

32/45>19/50>6/55; since the rate of single occupants in 1 bedroom apartments is higher than the rate of single occupants living in any type of apartment and a multiple-room apartment, the event that an apartment has 1 bedroom and 1 occupant is not indepenent.

What percentage of the data falls outside 1 standard deviation of the mean?

Alik [6]

We all know about the bell curve i.e. normal distribution curve. It is centered about the mean and spread equally on each side.

We describe the area of the curve with the help of standard deviations.

With in 1 standard deviation about the mean i.e. from -1 s.d. (left of mean) to +1 s.d. (right of mean), it covers 68% of the total area of curve.

So, the data that falls outside 1 standard deviation of the mean would be equal to (100% - 68%) i.e. 32%.

So, 32% is the final answer.
