Answer:
92%
Step-by-step explanation:
The percentage of apartments rented for less than $600 is given by the sum of all of the apartments in the 300 to 400, 400 to 500 and 500 to 600 intervals divided by the total number of apartments sampled (250).

92% of the apartments rented for less than $600.
Answer:

Step-by-step explanation:
there are 60 seconds in a minute so about 6 9 seconds in a minute. then there is 12 pages per 9 seconds and since there is 6 9 seconds then you can just multiply 6 by 9 to get the answer 72
Answer:

Step-by-step explanation:
First of all we need to know when does two events become independent:
For the two events to be independent,
that is if condition on one does not effect the probability of other event.
Here, in our case the only option that satisfies the condition for the events to be independent is
. Rest are not in accordance with the definition of independent events.
Answer:

Now we can find the limits in order to determine outliers like this:


So for this case the left boundary would be 3, if a value is lower than 3 we consider this observation as an outlier
b. 3
Step-by-step explanation:
For this case we have the following summary:
represent the minimum value
represent the first quartile
represent the median
represent the third quartil
represent the maximum
If we use the 1.5 IQR we need to find first the interquartile range defined as:

Now we can find the limits in order to determine outliers like this:


So for this case the left boundary would be 3, if a value is lower than 3 we consider this observation as an outlier
b. 3
