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.

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)
