In class, we discussed how to present discrete & non-discrete data in a frequency table.
Attempt the following in your MATHS NOTEBOOK
(a) Frequency Table (Discrete Data)
Question1
Textbook 1B: Chapter 16 Data Handling - Basic Practice 1 Q2
The following list shows the number shown on a dice for each of 40 tosses:
1 6 4 2 5
3 3 3 6 5
2 5 2 4 2
1 1 6 5 2
1 3 3 1 3
6 4 4 5 2
3 1 1 6 4
3 4 6 5 2
(a) Construct a frequency table for the data.
(b) Find the number of tosses for which the number shown on the dice is a PRIME number.
Question 2
Basic Practice 1:
Textbook 1B: Chapter 16 Data Handling - Further Practice 1 Q5
The following list shows the distances (in km) covered by 30 passengers who took taxis.
7.2 2.8 4.2 6.0 6.5 3.3 5.3 9.0 7.1 0.8
4.1 3.7 8.1 3.6 4.7 6.4 8.4 1.5 5.5 7.9
9.3 5.8 6.9 5.7 1.6 2.3 4.8 4.0 9.2 6.5
(a) Construct a frequency table of uniform intervals for the data, using the intervals 0 < x ≤ 2, 2 < x
≤ 4 and so on.
(b) Find the percentage of passengers who covered more than 6 km.
Note: Let x represents the distance covered by the passenger.
