The slope of the line that passes through the points (x1, y1) and (x2,y2) is computed as follows:
In this case, the points are (24, 28) and (8,8), then its slope is:
The slope-intercept form of a line is:
y = mx + b
where m is the slope and b is the y-intercept
Substituting into the general equation with m = 5/4 and the point (24, 28) we get:
Finally, the equation is
y = 5/4x - 2
Answer: No, the means in the two studies significantly is not different at the 95% confidence level.
Step-by-step explanation:
Since we have given that
Study 1,
Mean = 30.8,
Standard Deviation = 6.2,
Sample size = 100
And
Study 2
Mean = 32.2,
Standard Deviation = 5.4,
Sample size = 200
So, Hypothesis would be
So, At 95% confidence level, z = 1.96
So, the test statistic value would be
Since 1.96>-1.9228
So, we will accept the null hypothesis.
Hence,No, the means in the two studies significantly is not different at the 95% confidence level.
