Answer:
C
Step-by-step explanation:
The line crosses the y-axis at 3, and has a slope of -1/5. You can use the formula y=mx+b where m represents the slope and b is the point at which the line crosses the y-axis.
Answer:
92
Step-by-step explanation:
Max= biggest number, surely?
Answer:
The lower bound of the 95% confidence interval for the mean sale time for all homes in the neighborhood is of 160 days.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
That is z with a pvalue of 
, so Z = 1.96.
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 190 - 30 = 160 days
The lower bound of the 95% confidence interval for the mean sale time for all homes in the neighborhood is of 160 days.
The x-intercept is (4,0).
The y-intercept is (0,6).
Let's differentiate the terms statistic and parameter. Statistic is a branch of mathematics that involves the treatment of various data through collection, preparation, analysis and interpretation. A parameter is a unit of measure which is an element of the system.
Since 78% is the percentage of the whole data, this is a statistic. A parameter, for instance, is the 2,890 readers :)
The answer is A.
I hope you clearly understood my explanation :)
