Assume that the distributions of x and y are n(μx, σ2) and n(μy, σ2), respectively.
given the nx = 4 observations of x,

134, 151, 156, 157

and ny = 6 observations of y,
128, 139, 163, 171, 172, 176 find the p-value for the test h0: μx = μy vs. h1: μx ≠ μy. round your answer to 3 decimal places. hint 1: assume the population variances are equal. hint 2: excel: =tdist(t, degrees of freedom,1) gives area to the right of t; =tdist(t, degrees of freedom,2) gives 2×(area to the right of t). or r: pt(t, degrees of freedom) gives area to the left of t.
