  1. Two independent simple random samples are taken to test the difference between the means of two populations. The standard deviations are not known but are assumed to be equal. The sample sizes are n₁ = 15 and n₂ = 35. The correct distribution to use is the:
    a) t distribution with 51 degrees of freedom
    b) z distribution with 50 degrees of freedom
    c) z distribution with 49 degrees of freedom
    d) t distribution with 48 degrees of freedom
