Question

the residents of three towns were polled to find the percentage of residents who take a vacation in the summer or in the winter.

vacations

	summer	winter	total
town 2	345	102	447
town 3	143	158	301
total	1,055	347	1,402

which is the joint relative frequency of those in town 2 who take a summer vacation? round the answer to the nearest percent.

Explanation:

Step1: Recall joint relative frequency formula

Joint relative frequency for a cell is \(\frac{\text{Cell Frequency}}{\text{Total Frequency}}\).

Step2: Identify values

Cell frequency (Town 2, Summer) = 345, Total frequency = 1402.

Step3: Calculate the ratio

\(\frac{345}{1402} \approx 0.246\)

Step4: Convert to percentage and round

\(0.246\times100 = 24.6\%\), rounded to nearest percent is \(25\%\).

Answer:

25%
