Find the range and the mode for the data

Range = 7

Mode = 1

Step-by-step explanation:

Given the data

8, 1, 1, 6, 2, 2, 1, 1,8

Range = Highest value in the data - Lowest value in the data

Highest value = 8

Lowest value = 1

Range = 8 - 1

Range = 7

The mode is the data value that is occurring most. from the set of data, we can see that 1 is occurring four times (most frequent). Hence the mode of the data is 1

A stenographer will type 80 words.

Step-by-step explanation:

In this question it is given that average typing speed of a stenographer is 100 words per minute and we have to calculate the words a stenographer will type in 4/5 of a minute.

By using unitary method we will calculate the number of words a stenographer will type.

∵ In 1 minute stenographer is typing words = 100

∴ in 4/5 minutes stenographer will type = 100 × (4/5) words

                                                                  = 400/5 = 80 words

So the answer is a stenographer will type 80 words in 4/5 of a minutes.
