The weight (in pounds) for a population of school-aged children is normally distributed with a mean equal to 133 ± 25 pounds (μ ± σ). suppose we select a sample of 100 children (n = 100) to test whether children in this population are gaining weight at a 0.05 level of significance. part (a) what are the null and alternative hypotheses? h0: μ ≤ 133 h1: μ > 133 h0: μ = 133 h1: μ < 133 h0: μ = 133 h1: μ ≠ 133 h0: μ ≤ 133 h1: μ = 133
