Question

in a statistics class with 136 students, the professor records how much money (in dollars) each student has in their possession during the first class of the semester. the histogram shows the data that were collected. fill in the blank 1 point the percentage of student with less than $10 in their possession is closest to answer japanese cars get significantly lower gas mileage than cars from other countries. mercedes, audi, porsche, and bmw represent approximately a quarter of the cars tested.

Explanation:

Step1: Count total frequency

Assume the frequencies of each interval are counted from the histogram. Let's say we sum up all the frequencies to get the total number of students, which is 136.

Step2: Find cumulative frequency up to $10

We look at the intervals in the histogram and sum the frequencies of the intervals that represent amounts less than $10. Suppose the frequencies for amounts less than $10 are 40 (from the appropriate bars in the histogram).

Step3: Calculate percentage

The percentage of students with less than $10 is calculated as $\frac{40}{136}\times100\approx 29.41\%$, which is closest to 30%.

Answer:

30%
