Answer 1

Answer:

a number is the answer of this question

Answer 2

The values are

a) Range=20

b) Arithmetic Mean=33.5

c) Median=36

d) Mode=34

Step-by-step explanation:

Given that the marks scored by 11 students in mathematics test are below :

34,37,30,38,50,34,34,38,36,45,31

To find the a) range b) arithmetic mean c) median d) mode

a) Range

First arrange the given data from least to greatest

That is in ascending order

30,31,34,34,34,36,37,38,45,50

Range is the difference of greatest value from the least

Range =50-30

Therefore range =20

b) Arithmetic mean

Arithmetic mean

Therefore Arithmetic mean=33.5

c) Median

Median is the middle value from the given data set

Therefore median=36

d) Mode

Mode is the repeating value in the given data set

Therefore mode=34
