Explain why the t-distribution has less spread as the number of degrees of freedom increases. choose the correct answer below. a. the t-distribution has less spread as the degrees of freedom increase because, as n increases, less information is known about sigmaσ by the law of large numbers. b. the t-distribution has less spread as the degrees of freedom increase because, for large values of n, ngreater than or equals≥30, the t-distribution and the normal distribution are the same. c. the t-distribution has less spread as the degrees of freedom increase because, as n increases, s becomes closer to sigmaσ by the law of large numbers. d. 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.
