Explain why the t-distribution has less spread as the number of degrees of freedom increases. Choose the correct answer below. O A. The t-distribution has less spread as the degrees of freedom increase because, as n increases, s becomes closer to o by the law of large numbers. OB. The t-distribution has less spread as the degrees of freedom increase because the variability introduced into the t-statistic becomes greater as n increases. O C. The t-distribution has less spread as the degrees of freedom increase because, for large values of n, n2 30, the t-distribution and the normal distribution are the same. O D. The t-distribution has less spread as the degrees of freedom increase because, as n increases, less information is known about o by the law of large numbers.
