Question
A nutritionist need to study the daily protein intake of a client (during 3 week period), present in different food items and the data collected by him is as follows:32, 21, 12, 43, 16, 48, 56, 24, 40, 45, 34, 11, 43, 33, 25, 34, 55, 32, 22, 20, 42Making 6 class intervals for the range, the length of each interval would approximately be _______.Select one:a.4b.10c.8d.5
Solution
To find the length of each interval, you first need to find the range of the data. The range is the difference between the highest and lowest values. In this case, the highest value is 56 and the lowest is 11. So, the range is 56 - 11 = 45.
Next, you divide the range by the number of class intervals. The question states that there are 6 class intervals. So, you divide 45 by 6, which equals 7.5.
However, since the length of each interval should be a whole number, we round up to the nearest whole number, which is 8.
So, the length of each interval would approximately be 8.
Therefore, the correct answer is c. 8.
