The food services division of Cedar River Amusement Park, Inc., is studying the amount that 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:

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

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 15-25, 25-35,........,75-85

Now the frequency distribution is

Class interval |
Frequency |

15-25 |
1 |

25-35 |
2 |

35-45 |
5 |

45-55 |
10 |

55-65 |
14 |

65-75 |
5 |

75-85 |
3 |
