Answer:
Step-by-step explanation:
we know that
If two lines are parallel then their slopes are equal
The equation of the given line is
the slope is
so
the slope of the parallel line to the given line is also
Find the equation of the line that is parallel to the given line and passes through the point (6, 5)
we have
The equation of the line in point slope form is
substitute
Convert to slope intercept form
isolate the variable y
Answer:
The margin of error for the 99% confidence level for this sample is ±2.23.
None of the given figures is close to the answer:
E. None of the above
Step-by-step explanation:
margin of error (ME) around the mean can be calculated using the formula
ME= where
- z is the corresponding statistic of the 99% confidence level (2.576)
- s is the population IQ standard deviation (15)
- N is the sample size (300)
Using these numbers we get:
ME= ≈ 2.23
