The median is the value that can be found in the middle of any data set. After plotting the values on the line plot (shown in the attached image), we can write out our data (shown under neath the line plot).
Then, we start by crossing off one value on each side of the data to work our way towards the middle. Once we come to the middle, we see that there are two values in the middle: 6 and 6.
To find the median when we have two values in the middle, we must add them, then divide by two.
6 + 6 = 12
12 ÷ 2 = 6
So, the median for this data set is 6.

Answer:
a. The probability that a particular student arrives by car is = 0.05, which equals 5%.
b. The probability that a particular student walks to school is = 0.3, which equals 30%.
c. The probability that a particular student does not walk to school is = 0.7, which equals 70%.
d. The probability that a particular student does not walk or come by car is = 0.65, which equals 65%.
Step-by-step explanation:
Probability is the greater or lesser possibility of a certain event occurring. In other words, probability establishes a relationship between the number of favorable events and the total number of possible events. Then, the probability of any event A is defined as the quotient between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.
In this case, the number of possible cases is always the same, which is equal to the total number of students. So the number of possible cases is 320 students. The number of favorable cases varies as follows:
a. Number of favorable cases= number of students that arrive by car= 16
So:
P(A)= = 0.05, which equals 5%
<u><em>The probability that a particular student arrives by car is </em></u><u><em> = 0.05, which equals 5%.</em></u>
b. Number of favorable cases= number of students that walk to school= 96
So:
P(A)= = 0.3, which equals 30%
<u><em>The probability that a particular student walks to school is </em></u><u><em> = 0.3, which equals 30%.</em></u>
c. Number of favorable cases= number of students that do not walk to school = 320 students - number of students that walk to school= 320 students - 96 students= 224 students
So:
P(A)= = 0.7, which equals 70%
<u><em>The probability that a particular student does not walk to school is </em></u><u><em> = 0.7, which equals 70%.</em></u>
d. Number of favorable cases= number of students that do not walk or come by car= 320 students - number of students that walk to school - number of students that arrive by car= 320 students - 96 students - 16 students= 208 students
So:
P(A)= = 0.65, which equals 65%
<u><em>The probability that a particular student does not walk or come by car is </em></u><u><em> = 0.65, which equals 65%.</em></u>
