Determine the class boundaries by subtracting 05 05 from the lower class limit and by adding 05 05 to the upper class limit. The cumulative frequency of a data class is the number of data elements in that class and all the previous classes. Mark the cumulative frequency on the vertical axis or y-axis.
This result shows you that ten gas stations prices are between 350 and 399. 5th class 102-119 frequency 4 38 add 4th class frequency and all of them below it. You can put this solution on YOUR website.
Correct option is C The fifth class has the interval. Start with 0 0 and create 4 4 groups of size 3 3. 0 0 Similar questions Class intervals in a frequency distribution are 3671011141518 etc.
Calculate the relative frequency of the second class. Find the max and min. If we calculate the size of the class interval for each class in the frequency distribution well find that each class interval has a size of 4.
6 4 5 5 20. Is the percentage of data that fits in that class. Experts are tested by Chegg as specialists in their subject area.
12001299 Thus the upper limit of the class is 1299 Was this answer helpful. Determine the frequency of the fifth class. 96 150 The range is Round up to 60.
How do you calculate the relative frequency of a class. Here if we take length of class interval as 10 then the number of class interval will be 5510 55 or 6 which is less than the desired number of classes. 5 13 20 32 60 80 90 100 The cumulative frequency is calculated by adding each frequency from a frequency distribution table to the sum of its predecessors.
Similarly the size of the class interval for the second class is 31 35 4. For the first class 300 399 The class width Upper class boundary lower class boundary Upper class boundary 3995 Lower class boundary 2995 Therefore the class width 3995 2995 100. Determine your answer as a simplified fraction.
The following data describes percentage of satisfied customers at Burger Barn. Compute the cumulative frequency of the second class. The actual upper limit of the class interval 710 is.
With a sample size of 20 gas stations the relative frequency of each class equals the actual number of gas stations divided by 20. The sum of the relative frequencies 1. Therefore the relative frequency is 550 010 10.
Determine your answer as a simplified fraction. In the second line. 1 First Class Frequency f 1 14 2 Second Class Frequency f 2 12 3 Third Class Frequency f 3 7 4 Fourth Class Frequency f 4 3 5 Fifth Class Frequency f 5 4.
In this example for the 375 to 399 class you add its class frequency 4 to the frequency of the previous class 350 to 374 which is 6 so 64 10. Plot the points x y in the coordinate plane where x represents the upper limit value and y represents the cumulative frequency.

Calculate the relative frequency of the fifth class. Relative frequency of a class. Determine your answer as a simplified.
Complete the frequency table for this data. Finally join the points and draw the smooth curve. Height of eruption in 127 96 110 150 140 110 100 130 110 126 135 116 118 129 128 120 135 130 102 141 Answer by Fombitz 32380 Show Source.
Class Frequencyf Cumulative Frequency 1217 3 3 1823 6 36 2429 4 364 3035 2 3 642 Class Frequency f Cumulative - Frequency 12 - 17 3 3 18 - 23 6 3 6 24 - 29 4 3 6 4 30 - 35 2 3. Find class frequency for each class. How to enter data as a cumulative frequency table.
10 20 30 40 50 60 70 80 cf. The sum of the percentages 100. Step 6 of 7.
For example you calculate the relative frequency of prices between 350 and 374 as 620 to get 030 30 percent. The following table shows how to calculate the midpoint of. Consider the following data representing the price of refrigerators in dollars.
We review their content and use your feedback to keep the quality high. 4 4 Provide an appropriate response. The end of each class interval would be 10705 72 11425 11425 72 12145 12145 72 12865 12865 72 13585 13585 72 14305 The frequency for the fifth class that is between 13585 to 14305 would be 2 Advertisement.
The modal class in the following frequency distribution is A 30 40 B 40 50 C 50 60 asked Dec 16 2021 in Statistics by SatyamSarangi 323k points statistics. C approximate the relative frequency of the fifth class. 111410338 The following data describes percentage of satisfied customers at Touchdown Sporting Goods.
B approximate the greatest and least relative frequencies. What is the frequency of the 5th class. Determine the lower class boundary for the sixth class.
You can find the midpoint of each class by adding the lower class limit and the upper class limit then dividing by two. Class ClassBoundaries Frequency 0 2 3 5 6 8 9 11 Class Class Boundaries Frequency 0 - 2 3 - 5 6 - 8 9 - 11. Use the relative frequency histogram to a identify the class with the greatest and the class with the least relative frequency.
The result is then expressed as either a fraction or a percentage. The curve so obtained gives a cumulative frequency distribution graph of less than type. For example the size of the class interval for the first class is 30 26 4.
Determine the class width of the classes listed in the frequency table. Using the table above find the class width for the first class. 421019 Step 7 of 7.
Class midpoint lower class limit upper class limit 2. If we take class length of 5 then the number of classes will be 555 11 which is 1 less than the actual number of classes shown in Table 26 namely 12. Dividing by 5 would make a class width of 12.
Determine the upper class boundary for the fourth class. 965 994 967 936 965 992 905 958 919 993 949 912 924 904 959 975 975 950. Complete the frequency table for this data.
