1. The problem is to determine the percentage of radios from each brand that are likely to play 30 minutes or longer based on the given data and box plot description.
2. First, let's analyze the Secure Hike Emergency Radio 4.0 data: 21, 22, 24, 25, 25, 25, 25, 26, 27, 29, 30, 30, 30, 30, 33.
3. Count how many values are 30 minutes or longer: 30, 30, 30, 30, 33. There are 5 such values out of 15 total.
4. Calculate the percentage for Secure Hike: $$\frac{5}{15} \times 100 = 33.33\%$$.
5. Now analyze the X-Treamline Crank Radio data: 25, 25, 27, 27, 28, 29, 30, 30, 30, 34, 36, 36, 38, 39, 42.
6. Count how many values are 30 minutes or longer: 30, 30, 30, 34, 36, 36, 38, 39, 42. There are 9 such values out of 15 total.
7. Calculate the percentage for X-Treamline: $$\frac{9}{15} \times 100 = 60\%$$.
8. Comparing these percentages to the answer options, the closest match is "50% of X-Treamline Crank Radios ARE LIKELY to play 30 minutes or longer, while only 25% of Secure Hike Emergency Radios ARE LIKELY to play 30 minutes or longer." This option approximates the percentages reasonably given the data and box plot medians.
Final answer: 50% of X-Treamline Crank Radios and 25% of Secure Hike Emergency Radios are likely to play 30 minutes or longer.
