Let x be a random variable representing the amount of sleep each adult in new york city got last night. consider a sampling distribution of sample means x. (a) as the sample size becomes increasingly large, what distribution does the x distribution approach? uniform distribution sampling distribution normal distribution binomial distribution (b) as the sample size becomes increasingly large, what value will the mean μx of the x distribution approach? μx μ μ/√n μ/n σ (c) what value will the standard deviation σx of the sampling distribution approach? σ/n σx σ/√n μ σ (d) how do the two x distributions for sample size n = 50 and n = 100 compare? (select all that apply.) the standard deviations are μ / 50 and μ / 100, respectively. the means are the same. the standard deviations are the same. the standard deviations are σ / √50 and σ / √100, respectively. the standard deviations are μ / √50 and μ / √100, respectively. the standard deviations are σ / 50 and σ / 100, respectively.
