A researcher is interested in determining whether a new drug lowers blood pressure more than a leading drug. The average systoli
c blood pressure was analyzed for 10 people using the drugs. The mean systolic blood pressure of the people using the new drug is 121.7 millimeters of mercury whereas the mean systolic blood pressure for those using the leading drug was 123.1 millimeters of mercury. After rerandomizing the data 100 times, the following dot plot was generated.
Hint: where SD is the standard deviation, XH is the high value, and XL is the low value
Hint: where SD is the standard deviation and N is the sample size
What is the margin of error, rounded to the nearest hundredth, for this experimental study?

Answer:
Step-by-step explanation:
2 + m
Rewrite with variable first.
m + 2
m + 2
Can’t be simplified further.
m - (-2)
Distribute negative sign.
m + 2
-2-m
Rewrite with variable first.
-m - 2
The last expression is not equivalent to m+2.
Answer:
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
You need to find slope of the line with the formula:
Pick to points of the given line. You can choose the point (60,3) and the point (30,2).
Then, substituting into the formula:
You can observe in the graph that the line intercepts the y-axis at the point (0,1), therefore "b" is:
Substituting the slope and the y-intercept found into , you get the equation of this line:
Where "y" represents the Height (1,000 ft) and "x" represents the Time in seconds.
We need slope of all lines ?
- J(-5,-1)
- K(0,1)
- L(2,-5)
Slope of JK:-
Slope of KL:-
