What is the median of the following numbers 3 31 37 56 61 57 62.

The median is 56

Step-by-step explanation: The median is the middle number after you organize the numbers from least to greatest.

We have the following numbers: 3, 31, 37, 56, 61, 57, 62

Now, sort them from least to greatest: 3,31,37,56,57,61,62

Now simply cross off one from each side, until you find the median.

3,31,37,56,57,61,62

31,37,56,57,61

37,56,57

56

So, the median of the following numbers above is 56.

the answer is c.

step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
