Here, h = 160 – 150 = 10

Then,

**Question 6**

In a study of diabetic patients in a village, the following observation were noted .

Age in year | 10-20 | 20-30 | 30-40 | 40-50 | 50-60 | 60-70 |

No. of patients | 2 | 5 | 12 | 19 | 9 | 4 |

Represent the above data by a frequency polygon.

**Answer 6**

Represent the above data by a frequency polygon –

We plot the following points on the graph : (5, 0), (15, 2), (25, 5), (35, 12), (45, 19), (55, 9), (65, 4) and (75, 0) and join them to form a frequency polygon as given below :

**Question 7**

The ages of 360 patient treated in a hospital on a particular day are given below .

Age in year | 10-20 | 20-30 | 30-40 | 40-50 | 50-60 | 60-70 |

No. of patients | 90 | 40 | 60 | 20 | 120 | 30 |

Draw a histogram and a frequency polygon on the same graph to represent the above data.

**Answer 7**

We plot the following points on the graph : (5, 0), (15, 90), (25, 40), (35, 60), (45, 20), (55, 120), (65, 30) and (75, 0) and join them to form a frequency polygon :

**Question 8**

Draw a histogram and the frequency polygon from the following data .

Class-interval | 20-25 | 25-30 | 30-35 | 35-40 | 40-45 | 45-50 |

Frequency | 30 | 24 | 52 | 28 | 46 | 10 |

**Answer 8**

We plot the following points on the graph :

(17.5, 0), (22.5, 30), (27.5, 4, 24), (32.5, 52), (37.7, 28), (42.5, 46), (47.5, 10) and (52.5, 0) and join them to form a frequency polygon :

Class-interval | 400-450 | 450-500 | 500-550 | 550-600 | 600-650 | 650-700 | 700-750 |

Frequency | 16 | 25 | 40 | 32 | 18 | 27 | 9 |

**Answer 10**

The table in cumulative frequency form,

Now, plot the point (450, 16), (500, 41), (550, 81), (600, 113), (650, 131), (700, 158) and (750, 167) on the graph and join them in free hand to get an ogive as shown in the figure.

**Question 11**

Draw an ogive for the following frequency distribution .

Marks obtained | Less than 10 | Less than 20 | Less than 30 | Less than 40 | Less than 50 |

No. of student | 8 | 23 | 43 | 50 | 64 |

**Answer 11**

The cumulative frequency table :

Plot the point (10, 8), (20, 23), (30, 43), (40, 50) and (50, 64) on the graph and join them to from an ogive.

**Question 12**

Draw an ogive for the following frequency distribution .

Class-interval | 10-19 | 20-29 | 30-39 | 40-49 | 50-59 |
