Answer:
The 95% confidence interval for the measurements is [48.106, 53.494].
Step-by-step explanation:
The average M of this sample is
The standard deviation s of this sample is
The degrees of freedom are
Then, the critical value of t for a 95% CI and 4 degrees of freedom is t=2.776.
The margin of error of the CI is:
Then, the lower and upper bounds of the CI are:
The 95% confidence interval for the measurements is [48.106, 53.494].
After 75% increase followed by a 33 1/2% decrease the net increased is 16.375%.
<u>Solution:</u>
Need to determine net percentage increase or decrease when a value is increased by 75% and then decreased by that is 33.5%.
Let’s assume initial value be represented by variable x.
Now there is decrease of 33.5%
Hence after 75% increase followed by a decrease the net increased is 16.375%.
The slopes of perpendicular lines are negative reciprocal to each other
ex. the negative reciprocal to 5/2 is -2/5
once you find the perpendicular slope, you plug in the point and slope into the point-slope form of a line and then rearrange it into the slope-intercept form to get your answer
point slope
slope intercept form
