Used invT like thwy wanted keep getting a domain error? thanks PermafreshHylite146190141183153176109148102A manufacturer wants to know how large is the difference in mean wrinkle recovery angle.a. The mean and the standard deviation for the Permafresh are:x =130.2V Round to 3 decimal places.S =23.08Round to 3 decimal places.b. The mean and the standard deviation for the Hylite are:x =174.25Round to 3 decimal places.S =18.410Round to 3 decimal places.c. The standard error is:SE =13.830Round to 3 decimal places.The critical value from the distribution for a confidence interval of 99.8% is:t*:DNEx Use degrees of freedom of 3. Use Technology Round to 3 decimal places.d. Using the the answer from above (all rounded to 3 decimal places), calculate by hand a 99.8%confidence interval for the difference in mean wrinkle recovery angle:toHint Round to 3 decimal places.

The data shows the Permafresh and Hylite.
