Construct the cumulative frequency distribution for the given data.
Daily Low: Frequently:
35-39 2
40-44 3
45-49 5
50-54 12
55-59 8
60-64 9
65-69 1
Daily low:
Less than 40
Less than 45
Less than 50
Less than 55
Less than 60
Less than 70
Construct the cumulative frequency distribution.
Cannot show the distribution on these posts.
To construct the cumulative frequency distribution, you need to start by organizing the data in ascending order.
Here is the given data organized in ascending order:
Daily Low: Frequently:
35-39 2
40-44 3
45-49 5
50-54 12
55-59 8
60-64 9
65-69 1
Step 1: Calculate the cumulative frequency by adding up the frequencies from the smallest data point to the largest data point.
Daily Low: Cumulative Frequency:
35-39 2
40-44 5 (2+3)
45-49 10 (5+5)
50-54 22 (10+12)
55-59 30 (22+8)
60-64 39 (30+9)
65-69 40 (39+1)
Step 2: Determine the cumulative frequency distribution by creating ranges and listing the cumulative frequencies within those ranges.
Daily Low: Cumulative Frequency Distribution:
< 40 2
< 45 5
< 50 10
< 55 22
< 60 30
< 70 40
So, the cumulative frequency distribution for the given data would be:
Daily Low: Cumulative Frequency Distribution:
< 40 2
< 45 5
< 50 10
< 55 22
< 60 30
< 70 40
