#### Question

The monthly maximum temperature of a city is given in degree celcius in the following data. By taking suitable classes, prepare the grouped frequency distribution table

29.2, 29.0, 28.1, 28.5, 32.9, 29.2, 34.2, 36.8, 32.0, 31.0, 30.5, 30.0, 33, 32.5, 35.5, 34.0, 32.9, 31.5, 30.3, 31.4, 30.3, 34.7, 35.0, 32.5, 33.5, 29.0, 29.5, 29.9, 33.2, 30.2

From the table, answer the following questions.

(i) For how many days the maximum temperature was less than 34^{o}C ?

(ii) For how many days the maximum temperature was 34^{o}C or more than 34^{o}C ?

#### Solution

The monthly maximum temperature of a city is given in degree celcius in the following data:

29.2, 29.0, 28.1, 28.5, 32.9, 29.2, 34.2, 36.8, 32.0, 31.0, 30.5, 30.0, 33, 32.5, 35.5, 34.0, 32.9, 31.5, 30.3, 31.4, 30.3, 34.7, 35.0, 32.5, 33.5, 29.0, 29.5, 29.9, 33.2, 30.2

The grouped frequency distribution table of the given data is as follows:

Class (Temperature) | Tally marks | Frequency |

28-29 | 2 | |

29-30 | 6 | |

30-31 | 5 | |

31-32 | 3 | |

32-33 | 5 | |

33-34 | 3 | |

34-35 | 3 | |

35-36 | 2 | |

36-37 | 1 | |

Total N = 30 |

(i) The number of days the maximum temperature was less than 34

(ii) The number of days the maximum temperature was 34

^{o}C = 2 + 6 + 5 + 3 + 5 + 3 = 24.(ii) The number of days the maximum temperature was 34

^{o}C or more than 34^{o}C = 3 + 2 + 1 = 6. Is there an error in this question or solution?

Solution The Monthly Maximum Temperature of a City is Given in Degree Celcius in the Following Data. Concept: Frequency Distribution Table.
