Can u please answer the question
1 answer:
Ok it is said that it is almost 15%
So we know how to round:
if it the rounding place value is 5 or more, we round upwards
If it is less than 5, it stays the same
So in this example:
The percentage is rounded up to the nearest whole number:
Look at the number after the decimal point.
14.1% ⇒ is closer to 14%
15.1% ⇒ is closer to 15%
15.8% ⇒ is closer to 16%
14.2% ⇒ is closer to 14%
14.3% ⇒ is closer to 14%
15.5% ⇒ is closer to 16%
14.4% ⇒ is closer to 14%
15.6% ⇒ is closer to 16%
14.5% ⇒ is closer to 15%
15.7% ⇒ is closer to 16%
14.6% ⇒ is closer to 15%
15.3% ⇒ is closer to 15%
14.7% ⇒ is closer to 15%
15.9% ⇒ is closer to 16%
14.8% ⇒ is closer to 15%
15.2% ⇒ is closer to 15%
14.9% ⇒ is closer to 15%
15.4% ⇒ is closer to 15%
These are the values that the percentage could have been to one decimal place:
15.1%, 14.5%, 14.6%, 15.3%, 14.7%, 14.8%, 15.2%, 14.9%, and 15.4%

Answer:
Mean of the data set in the dot plot would be: 3.6
Step-by-step explanation:
As we know that Mean from the dot plot can be obtained by:
- adding the numbers and then
- divide the resulting sum by the number of addends.
Please check the attached figure where the dot plot is also plotted.
From the dot plot, it is clear that
There are 3 dots at 1.
There are 4 dots at 2.
There are 3 dots at 3.
There are 4 dots at 4.
There are 5 dots at 5.
There are 3 dots at 6.
All we have to do is to add the dots and divide the sum by the number of addend dots.
In other words:
There are 3 dots at 1 ⇒ 1+1+1
There are 4 dots at 2 ⇒ 2+2+2+2
There are 3 dots at 3 ⇒ 3+3+3
There are 4 dots at 4 ⇒ 4+4+4+4
There are 5 dots at 5 ⇒ 5+5+5+5+5
There are 3 dots at 6 ⇒ 6+6+6
As there are total 22 dots.
And the sum of all the dots with respect to their plot number = 79
i.e. 1+1+1+2+2+2+2+3+3+3+4+4+4+4+5+5+5+5+5+6+6+6 = 79
Thus
Mean of the data set in the dot plot = 79/22
= 3.6
Therefore, Mean of the data set in the dot plot would be: 3.6
