Answer:
A frequency table is given below.
Step-by-step explanation:
Given the data
3,12,25,2,3,6,17,17,15,13,20,12,21,18,19
- The frequency distribution table provides us a general snapshot of the data using which we may be able to find certain patterns.
A frequency table is given by:
Class Count Percentage
0 - 6 4 26.7
7 - 13 3 20
14 - 20 6 40
21 - 27 2 13.3
Total 15 100
We have to find the probability N(11,2)>12, wherein N(11,2)
is the normal law with mean 11 and standard deviation 2.
Using a scientific calculator we get the probability 0.3.
Now multiply by the population which is 1000 like this:
0.3*1000=300.
There is 300 <span>spiders in the colony which weigh more than 12 grams</span>
Both mean and median are measures of the center of a set of data.
Mean is normally preffered to the median except if there is an outlier that has a tendency to affect the mean.
An outlier is a data point that significantly differs from the other data points in a sample.
In the data set above, there is no outlier that will affect the mean.
Therefore, he should use the mean because there are no outliers that affect the mean.
There are 1000 grams in a kg - so the dog weighs 15,000 grams. Add that to the collar weight (200g) and you get 15,200 grams.
