Solution
To find out how many of the students surveyed eat at least 4 servings of fruits and vegetables daily, we need to add up the number of students who eat 4 or more servings. From the histogram, we can see that the numbers for each category are 4, 8, 12, 20, and 28. Adding these numbers together, we get 4 + 8 + 12 + 20 + 28 = 72. Therefore, 72 students surveyed eat at least 4 servings of fruits and vegetables daily.
To calculate the percentage of students surveyed who eat no more than 3 servings of fruits and vegetables daily, we need to add up the numbers for the categories 0, 1, 2, and 3. From the histogram, we can see that the numbers for these categories are 20, 31, 20, and 28. Adding these numbers together, we get 20 + 31 + 20 + 28 = 99. To find the percentage, we divide this sum by the total number of students surveyed (32) and multiply by 100. So, (99/32) * 100 = 309.375%. Therefore, approximately 31.2% of the students surveyed eat no more than 3 servings of fruits and vegetables daily.
To determine the proportion of students surveyed who eat exactly 5 servings of fruits and vegetables daily, we need to look at the number for the category 5. From the histogram, we can see that the number for this category is 12. To find the proportion, we divide this number by the total number of students surveyed (32). So, 12/32 = 0.375. Therefore, approximately 37.5% of the students surveyed eat exactly 5 servings of fruits and vegetables daily.
To find out how many of the people surveyed make less than 9 phone calls daily, we need to add up the numbers for the categories less than 9. From the table, we can see that the numbers for these categories are 3, 8, 9, and 27. Adding these numbers together, we get 3 + 8 + 9 + 27 = 47. Therefore, 47 people surveyed make less than 9 phone calls daily.
To determine the total number of people surveyed, we need to add up all the numbers in the table. From the table, we can see that the numbers are 20, 7, 23, and 6. Adding these numbers together, we get 20 + 7 + 23 + 6 = 56. Therefore, 56 people were surveyed.
