Given:
The inequality is
Where, c is the number of cars in the parking lot.
To find:
The graph for the given inequality.
Solution:
We have,
Here, the value of c can be any real number less than or equal to 7. But c is the number of cars, so c must be a non-zero integer.
Since, all the non-zero integer values less than or equal to 7 are included in the solution set, therefore, c = 0,1, 2,3,4, 5,6,7.
In the graph of the given inequality, there are close circles on 0,1, 2,3,4, 5,6,7 as shown in option D.
Therefore, the correct option is D.
Answer: (1583.63, 1672.37)
Step-by-step explanation:
Given : Sample size : n= 83
Sample mean :
Sample standard deviation :
The population standard deviation is unknown .
The confidence interval for population mean :
For 90% confidence , significance level =
Using t-distribution table , Critical t-value =
, where n-1 is the degree of freedom.
Now , 90% confidence interval for the mean square footage of all the homes in that city will be :-
Hence, the 90% confidence interval for the mean square footage of all the homes in that city = (1583.63, 1672.37)
