1. Explain why the t-distribution has less spread as the number of dégrees af freedom increases. -A. The t-distribution has less spread as the degrees of freedom increase because, as

nincreases, s becomes closer to o by the law of large numbers.O B. The t-distribution has less spread as the degrees of freedom increase because, for largevalues of n, n2 30, the t-distribution and the normal distribution are the same.DC. The t-distribution has less spread as the degrees of freedom increase because, as nincreases, less information is known about o by the law of large numbers.D D. The t-distribution has less spread as the degrees of freedom increase because the variablityintroduced into the t-statistic becomes greater as n increases.
