Which scatter plot best illustrates a strong positive correlation?
1 answer:
Answer:
A
Step-by-step explanation:
You want to select the scatter plot with strong positive correlation.
<h3>Correlation</h3>Correlation is a measure of how well one variable's values track the values of another variable. Perfectly correlated variables will have a scatter plot that is a straight line. The sign of the correlation (positive, negative) matches the sign of the slope of the line.
The less correlated values are, the more their scatter plot looks like a random placement of points. When there is no correlation at all, knowing the value of one of the variables gives no clue about the value of the other one.
Computed values of correlation range from -1 to +1.
<h3>Strong positive correlation</h3>When the plot begins to resemble a line with positive slope, the variables plotted in the scatter plot have strong positive correlation. That is shown in the attached scatter plot.

Step-by-step explanation:
So we need to see how many tiles are left.
100 - 6 = 94
So we have 94 tiles. 2 of them are blank, so the chance of one being blank is:
2 / 94 which is
And that is our answer! Hopefully this helps, have a nice day :D

Answer: C. 7.5
Answer:
The population mean height of men in the village is 5.78 feet.
The sample mean height of men in the village is 7.8 feet.
Step-by-step explanation:
It is provided that the researcher's interest is in knowing the average height of the men in a village.
To the researcher, the population of interest is the <em><u>men</u></em><em> </em>in the village, the relevant population data are the <em><u>height of men</u></em> in the village, and the population parameter of interest is the <em><u>mean height of men</u></em>.
It is also provided that there are 590 men in the village, and the sum of their heights is 3,410.2 feet.
Compute the average height as follows:
Thus, the population mean height of men in the village is 5.78 feet.
It is given that the researcher measured the heights of 18 village men and calculated the average to estimate the average height of all the village men.
The sample for his estimation is <em><u>18 men</u></em>, the relevant sample data are the <em><u>heights of the 18 men</u></em>, and the sample statistic is the <em><u>sample mean height</u></em>.
It is also given that the sum of the heights of the 18 village men is 104.4 feet.
Compute the average height of the 18 men as follows:
Thus, the sample mean height of men in the village is 7.8 feet.
