Final Answer:
a. 20 students surveyed eat at least 4 servings of fruits and vegetables daily.
b. 62.5% of the students surveyed eat no more than 3 servings of fruits and vegetables daily.
c. The proportion of students surveyed who eat exactly 5 servings of fruits and vegetables daily is 0.094 or 9.4%.
Step-by-step explanation:
a. To determine the number of students eating at least 4 servings, add the frequencies of the bars corresponding to 4, 5, 6, and 7 daily servings, which equals 20 students.
b. To find the percentage of students eating no more than 3 servings, sum the frequencies of the bars for 0, 1, 2, and 3 daily servings (10 + 3 + 5 + 2 = 20), then divide it by the total number of students surveyed (32) and multiply by 100 to get 62.5%.
c. To compute the proportion of students eating exactly 5 servings daily, observe the frequency of the bar representing 5 servings (5 students) and divide it by the total number of students surveyed (32), resulting in 0.15625 or approximately 0.094 when rounded to three decimal places, which is equivalent to 9.4%.
