To find the slope of a line, we can use the following formula:
m-term stands for slope or gradient. The formula is useful whenever you want to find a slope of two points.
Let these be the following:
Substitute the points in formula:
Negative multiply negative always come out as positive.
Since m stands for slope, we can say that:
Answer:
The correct option is B
Step-by-step explanation:
From the question we are told that
The sample size is
The proportion that choose to vaccinate the teen boys is
considering the first statement
The 95% confidence interval is 12% ± the margin of error*standard deviation is false because
The 95% confidence interval is is %12 ± the margin of error
considering the second statement
The confidence interval should not be calculated due to the small sample size is true because from the central limit theorem
np = 64 * 0.12 = 7.68
and this value is less than 10 hence the confidence interval should not be calculated
considering the third statement
A 99% confidence interval will be smaller than the 90% confidence interval is false
This is because as the confidence level increase (for example from 90% to 99%) the margin of error increase which increases the confidence interval
