Question

plans after high school

	college	not college	total
not travel	24	5	29
total	67	15	82

which is the marginal relative frequency for students who plan to attend college? round the answer to the nearest percent.
18%
22%
35%
82%

Explanation:

Step1: Recall marginal - relative frequency formula

Marginal relative frequency = $\frac{\text{Row/Column Total}}{\text{Grand Total}}$

Step2: Identify relevant values

The number of students who plan to attend college is 67 (column total for "College"), and the grand total of students is 82.

Step3: Calculate marginal relative frequency

Marginal relative frequency = $\frac{67}{82}\approx0.817$

Step4: Convert to percentage

$0.817\times100 = 81.7\%$, which rounds to 82%

Answer:

82%
