Please Use Matlab to do this problem:
The cross-sectional area measurements (??2) from 7 cells are asfollows:
? = [153.3 91.2 99.3 115.0 101.7 135.8 102.4 ]
Assuming the cross-sectional areas of the cells are normallydistributed, construct a two-sided 95% confidence interval for themean cross-sectional area of the entire batch.
Then, generate one figure:
Plot all 7 data points on x-axis, mark them with redcircles;
Plot the mean value, which is going to be the center of yourinterval, mark it with
blue x;
Plot the upper and lower limit of the interval, mark them withblack squares;
Have your x-axis range from 70 to 180;
Have your y-axis range from -1 to +1. (So, your x-axis will bein the middle of
your figure)
You can play with the line width and font to make your figuremore reader friendly.
