Question

In a student survey, fifty-two part-time students were asked how many courses they were taking this term. The (incomplete) results are shown below: Please round your answer to 4 decimal places for the Relative Frequency if possible. # of Courses Frequency Relative Frequency Cumulative Frequency 1 20 Correct .3846 Correct 20 2 19 0.3654 39 Correct 3 13 0.25 52 What percent of students take exactly one courses? 51.61 Incorrect%

Answer 1

Answer:

The percentage of students taking exactly one courses is 38.46%.

Step-by-step explanation:

The frequency distribution table provided for the number of courses taken by part-time students is as follows:

# of Courses      Frequency         Relative            Cumulative

                                                     Frequency          Frequency

________________________________________________

             1                    20                 0.3846                     20

             2                    19                 0.3654                     39

             3                    13                 0.2500                     52

        TOTAL               52                 1.0000

The relative frequency is actually the probability or chance of the particular class or category of a frequency distribution.

The probability of students taking exactly one courses is 0.3846.

Then the percentage of students taking exactly one courses is:

0.3846 × 100% = 38.46%

Thus, the percentage of students taking exactly one courses is 38.46%.
