equation below is used in hypothesis testing to compute the test statistic, t, for a single population. x ̅ is the sample mean, μ_o the population mean, s the sample standard deviation, and n the sample size. If n is increased by a factor of 10 and everything else is held constant, what happens to t? t = (x ̅ - μ_o) / (s ⁄ (√n))
