Pulse rate (per minute) of two groups of people (A & B) are recorded.

Group A: 62, 75, 71, 72, 70, 65, 77, 72, 67, 80, 77, 62, 71, 74, 79, 67, 80, 77, 61, 71, 74, 61, 70,

80, 72, 59, 78, 71, 72 and 60.

Group B: 55, 71, 73, 66, 59, 64, 75, 71, 65, 76, 73, 60, 71, 72, 74, 62, 78, 72, 55, 70, 64, 58, 80,

76, 70, 59, 64, 74, 66 and 56.

1. Construct a Frequency Table for both the groups.

2. Prepare required histograms for both the groups.

3. Calculate the mean using the frequency tables.

4. With the help of suitable test find the significance differences between these two groups

of people in case of their pulse rate under an appropriate hypothesis.
