Suppose we wish to test the hypotheses h0: μ = 10 versus ha: μ < 10, where μ represents the mean age of children not in high school who are members of a large gymnastics club in a metropolitan area. assume age follows a normal distribution with σ = 2. a random sample of 16 ages is drawn from the population, and we find the sample mean of these observations to be = 8.76. what is the value of the p-value?
