# The following are the ages of 300 patients getting medical treatment in a hospital on a particular day

Age (in years)10-2020-3030-4040-5050-6060-70

Number of patients 60 42 55 70 53 20

Form: Less than type cumulative frequency distribution

**Solution:**

Given, the data represents the ages of 300 patients getting medical treatment in a hospital on a particular day.

We have to form the cumulative frequency distribution of less than type.

Age in years |
Number of patients |
Cumulative frequency |

Less than 20 |
60 |
60 |

Less than 30 |
42 |
60 + 42 = 102 |

Less than 40 |
55 |
102 + 55 = 157 |

Less than 50 |
70 |
157 + 70 = 227 |

Less than 60 |
53 |
227 + 53 = 280 |

Less than 70 |
20 |
280 + 20 = 300 |

**✦ Try This: **The following are the ages of 300 patients getting medical treatment in a hospital on a particular day :

Age (in years) | Number of patients |

10 - 20 | 64 |

20 - 30 | 44 |

30 - 40 | 55 |

40 - 50 | 77 |

50 - 60 | 56 |

60 - 70 | 40 |

Form: Less than type cumulative frequency distribution.
