Answer:
It means that for every 1 unit of time, the equation shows an increase of 8.38 units of distance.
Step-by-step explanation:
Slope is . Any number that does not have a denominator technically has a denominator of 1. Therefore, your slope is actually
. That means you have a rise, or the vertical progression, of 8.38 while your run, or your horizontal progression, is 1. For every unit your line travels horizontally, it travels 8.38 units vertically. I hope this makes sense.
Answer:
, rounded up, if needed, citizens should be included in the sample, in which
is the standard deviation of the population.
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 = 2.056.
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.
Within 4 years of the actual mean
We have to find n for which M = 4. So
, rounded up, if needed, citizens should be included in the sample, in which
is the standard deviation of the population.
