"Durable press" cotton fabrics are treated to improve their recovery from wrinkles after washing. "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 a random sample of fabric specimens. Assume the populations are approximately normally distributed with unequal variances. A manufacturer believes that the mean wrinkle recovery angle for Hylite is better. A random sample of 25 Permafresh (group 1) and 20 Hylite (group 2) were measured. Test the claim using a 10% level of significance.

H₁: Select an answer μ₂ x̄₁ σ² s² p μ μ₁ x̄₂ ? ≤ > ≠ < = ≥ Select an answer x̄₂ x̄₁ s² σ² p μ₁ μ μ₂

Select the correct symbols.

Test Statistic= (Give answer to 4 decimal places)

p-value= (Give answer to 4 decimal places)

Based on the above we choose to Select an answer Reject the null hypothesis Accept the null hypothesis Fail to reject the null hypothesis Accept the alternative hypothesis

The correct summary would be: Select an answer There is not enough evidence to support the claim There is enough evidence to reject the claim There is not enough evidence to reject the claim There is enough evidence to support the claim that the mean wrinkle recovery angle for Hylite is better.
