Question

A guidance counselor compiles data relating a student's english grade to the number of languages studied. the results are shown in the frequency table below. a 4-column table with 3 rows titled english grade versus number of languages studied. the first column has no label with entries english only, english and another language, total. the second column is labeled 90 or above with entries 15, 110, 125. the third column is labeled lower than 90 with entries 105, 270, 375. the fourth column is labeled total with entries 120, 380, 500. the counselor converts the frequency table to a conditional relative frequency table by column. a 4-column table with 3 rows titled english grade versus number of languages studied. the first column has no label with entries english only, english and another language, total. the second column is labeled 90 or above with entries 0.12, 0.88, 1.0. the third column is labeled lower than 90 with entries 0.28, 0.72, 1.0. the fourth column is labeled total with entries x, y, 1.0. what is the value of x? 0.16 0.20 0.24 0.40

Answer 1

The value of x is 0.24. Option C is correct. The frequency table is used to find the relative frequency.

What is a frequency table?

A frequency table is a collection of things with the number of times they appear in the table. f is used to signify frequency.

The given data from the table is;

The subgroup count of the column =  120

The total count = 500

x is the relative frequency

The relative frequency is found as;

$\rm x = \frac{ subgroup \ count }{ total \ count } \\\\ x=\frac{120}{500} \\\\\ x = 0.24$

Hence the value of x is 0.24. Option C is correct.
