Answer:
The outlier on the the scatter plot is point L(6,2).
Step-by-step explanation:
M(3,3)
P(5,5)
N(5,7)
L(6,2)
Other points are : (1,3), (2,3), (2,4), (3,4), (3,5), (4,5), (4,6), (5,6)
Now, To find the outliers on the scatter plot we plot all the given points on the graph.
The resultant graph is attached below :
An outlier is a value in a data set that is very different from the other values. That is, outliers are values which are usually far from the middle.
As we can see the graph the point L(6,2) is the most unusual or the farthest point on the scatter plot as compared with all the other points on the scatter plot.
Hence, The outlier on the the scatter plot is point L(6,2).
Answer:
Step-by-step explanation:
Sample proportion p is the proportion of favourable numbers to total number in the sample
By central limit theorem and also approximation of binomial to normal , we have sample proportion for large number of samples will be normal
with mean = sample proportion
and std deviation =
Thus we find standard deviation of proportion sample is inversely proportional to the square of the sample size n.
It follows automatically that as sample size increases std deviation decreases.
Here from 80 sample size was made to 200
So std deviation would decrease automatically
