Using the information can you help me solve parts h and i.

Would a residual plot of this data have a pattern to do a linear regression?

Using the information can you help me solve parts h and i. If you could include instructions for ti-84 calculators so I can know how to solve problems like this in the future I would appreciate it!
r=-.9601
r^2=.9217
y^=-9.3x+101.3
h) Calculate the 5 residual values (to 1 decimal place) that would be used to make a residual plot by filling in the ordered pairs.

i) Calculate the standard deviation about the least squares line. Use formula Se=sqrt ssresid/n-2. Would a residual plot of this data have a pattern to do a linear regression?
Transcribed Image Text:if a defibrillator shock is administered very soon after cardiac arrest. The accompanying data give
y = survival rate (percent) and x = mean call-to-shock time (minutes) for a cardiac rehabilitation
center (in which cardiac arrests occurred while victims were hospitalized and so the call-to-shock
time tended to be short) and for four communities of different sizes: For this problem use your
calculators.
