Difference in wrinkle resistance, Basic Statistics

Difference in wrinkle resistance

Please show how you solve this,,

reducing wrinkles. of course, the eason for durable press treatment s to reduce wrinkling. wrinkle recovery angle measures how well a fabric recovers from wrinkles. higher is better. here are data on the wrinkle recovery angle (in degrees) for the same fabric swatches:

Permafresh	136	135	132	137	134
Hylite	143	141	146	141	145

Is there a significant difference in wrinkle resistance?

a) Do the sample means suggest that one process has better wrinkle resistance?

b) Make stemplots for both samples. there are no obvious deviations from normality.

c) Test the hypothesis H null: m1= m2 against the two-sided alternative. what do you conclude from part (a) and from the result of your test?
