How to construct frequency table with sturge approximation

The stages to utilize to construct a frequency distribution table utilizing Sturge's approximation are as follows:

<h3>How to construct a frequency distribution table?</h3>

The steps to create a frequency distribution table utilizing Sturge's approximation exist as follows;

Step 1: Estimate the range of the data:

This exists simply by finding the difference between the biggest and the least values.

Step 2: Decide on the inaccurate number of classes in which the provided data exist to be grouped. The formula for this is;

K = 1 + 3.322logN

where; K= Number of classes

logN = Logarithm of the whole number of observations.

Step 3: Specify the approximate class interval size:

This exists acquired by splitting the range of data by the number of classes and exists symbolized by h class interval size.

Step 4: Find the starting point:

The lower class limit should take care of the least value in the raw data.

Step 5: Determine the remaining class boundaries:

When you have reached the lowest class boundary, then you can count the class interval size to the lower class boundary to obtain the upper-class boundary.

Step 6: Circulate the data into separate classes.

Please help me with question 19

Ksenya-84 [330]

Alright, lets get started.

Suppose the smaller integer = n

So, larger integer will be = n+2

3 times of larger integer will be = $3(n+2)$

smaller integer is added into this , so

$n +3 (n+2)$

The result is 2 less than 5 times of smaller integer, so

$5n - 2$

Both are equal so,

$n + 3 (n+2) = 5n - 2$

$n + 3n + 6 = 5n - 2$

Rafael makde the mistake that he didn't put the larger integer into parenthesis like (n+2) , so three times will be 3 n + 6 as he got 3n + 2

So, the correct equation is

$n +3n +6 = 5n - 2$

Solving the equation

$4n + 6 = 5n - 2$

$n = 8$

So, saller integer is 8 and larger integer is $8 + 2 = 10$

So, both integers are 8 and 10. : Answer

Hope it will help :)

How many tickets were sold on Sunday? Thanks

Butoxors [25]

The answer is 210 children tickets were sold . if you multiply the first equation by 7 it would be 7x+7y=2590. then subtract equation 2 from 1 you will have 4x=840 so x=210. Also you can use substitution method.
