Answer:
A graph with points connected by lines to show how something changes in value:
• as time goes by,
• or as something else changes.
Step-by-step explanation:
To solve this problem, let us first assign some variables.
Let us say that:
d = represents the population density of the circular region
(in units of 513 people per square mile)
p = represents the population of the circular region (in
units of people)
r = is the radius of the circular region
Now we can see that if we divide p by d, we can get a value
which has a units of square mile. Thus the area of the region, hence:
Area = 79,000 people / (513 people per square mile)
Area = 154 square mile
The area of a circle has the formula:
Area = π r^2
Therefore calculating for r:
154 square mile = π r^2
r = 7 miles (ANSWER)
Answer:
The correct option is C) The results were not statistically significant but were practically significant.
Step-by-step explanation:
Consider the provided information.
They found that the difference in these shelf lives had a p-value of 0.24. Assume an α of 0.05.
We reject the null hypothesis if p value is less than α.
We are fail to reject null hypothesis if p value is greater or equal to α.
Here p value is greater than 0.05.
So, we do not reject null hypothesis and conclude that result is not statistically significant. But, there is a practical difference between 3 days and 7 days.
Therefore, the correct option is C) The results were not statistically significant but were practically significant.
