Elasticity is an important parameter of kernmantle ropes (used in climbing, caving, mountaineering, etc.). One of the ways of describing it is static elongation (measured under a resting load of 80 kg). Static elongation was measured for two random rope samples of two different types of weaving. type-1 6.346.16 6.326.21 6.36 6.43 6.026.216.47 6.216.49 6.21 6.16 6.196.29 6.33 6.51
type-2 6.38 6.54 6.496.476.46 6.46 6.52 6.356.33 |6.35 6.31 6.376.13 6.45

Required:
a. Assume that σ1 = σ2. Is there evidence to support the claim that type-2 ropes are more elastic than type-1?
b. Find the P-value for this test.
