Question

A relative frequency table is made from data in a frequency table.

Relative Frequency Table: A 4-column table with 3 rows. The first column has no label with entries likes S, T, total. The second column is labeled U with entries 26%, 21%, 47%. The third column is labeled V with entries 42%, k, 53%. The fourth column is labeled total with entries 68%, 32%, 100%.
What is the value of k in the relative frequency table? Round the answer to the nearest percent.

2%
11%
20%
33%

Answer 1

Answer:

k = 11  let me know if you don't understand how I got this.  

Step-by-step explanation:

I'm gonna write it out

 U V total

S  26 42 68

T   21 k 32

Total 47 53 100

So, you want to look at the column and row labeled total, this is the key.  for the row total, it sums up everything in the column above it.  so for the u column, the total value is 47 while the two values above it are 26  and 21.  These two values sum to 47.  This is the same for all other columns, and you can use the same reasoning with the total column as well summing rows.

This gives you two ways to solve for k.  either 21 + k = 32 or 42 + k = 53.  Either way gets you the answer k = 11

Answer 2

The value of k in the relative frequency table is 11%.

What is relative frequency?

The ratio of the frequency of a particular event in a statistical experiment to the total frequency.

           U        V            total

S         26      42           68

T         21        k            32

Total   47       53          100

As, when we add the column data 26+ 21 = 47 which shows that the total consist of sum of column data.

So,  

21 + k = 32

k = 11
