The food services division of Cedar River Amusement Park, Inc., is studying the amount families who visit the amusement park spend per day on food and drink. A sample of 40 families who visited the park yesterday revealed they spent the following amounts:
$77

a. Organize the data into a frequency distribution, using seven classes and 15 as the lower limit of the first class. What class interval did you select?
b. Where do the data tend to cluster?
c. Describe the distribution.
d. Determine the relative frequency distribution.
Step 1 of 4</p>
a) We have to organise the given data into frequency distribution
Here the highest value is 84 from the given data
The interval is starting from 15
The no.of classes is 7
Then the class interval are 1525, 2535,........,7585
Now the frequency distribution is
Class interval 
Frequency 
1525 
1 
2535 
2 
3545 
5 
4555 
10 
5565 
14 
6575 
5 
7585 
3 
Total 
40 
Step 2 of 4</p>
b) we have to find where the data tend to cluster
Here from the frequency distribution the highest frequency corresponds to the class 5565
Hence the data is clustered at 5565
