Question

a random sample of students was surveyed and asked to list their grade level and whether or not they have a pet. results are shown in the table below. pets survey | pets | no pets 6th grade | 11 | 23 7th grade | 15 | 19 8th grade | 14 | 28 what percent of the 7th graders dont have pet? round your answer to the nearest tenth of a percent. answer

Explanation:

Step1: Find total 7th graders

To find the total number of 7th graders, we add the number of 7th graders with pets and without pets. From the table, 7th graders with pets are 15 and without pets are 19. So total 7th graders = \(15 + 19 = 34\).

Step2: Calculate percentage of 7th graders without pets

The formula for percentage is \(\frac{\text{Number of 7th graders without pets}}{\text{Total number of 7th graders}} \times 100\). Substituting the values, we get \(\frac{19}{34} \times 100\).

Step3: Compute the value

Calculating \(\frac{19}{34} \approx 0.5588\), then multiplying by 100 gives \(0.5588\times100 = 55.88\%\). Rounding to the nearest tenth of a percent gives \(55.9\%\).

Answer:

\(55.9\%\)
