which distribution is closer to the population variance? when the sample is 30 the mean of the sample variance ____ is why is the _t_ distribution larger than the _z_ distribution? why is z distribution compared to t_ distribution why is the sample variance much larger than the population variance why does the sample variance of the population variance look so similar to the _t_ distribution if population variance is small, t distribution is larger than variance how wide does sample variance need to get why does the _t_ distribution change from the _z_ distribution? what is the difference between a t and a z distribution when sample size is 30 the estimated variance should be which distribution has less sd of variance/sp which distribution looks the same as the z distribution why is the _t_ distribution larger than the sample variance? what is the _t distribution how to find variance of sample variance when population variance is large, the distribution is larger than the sample variance. when sampling sample size is 30 the _t_ distribution will appear more like the which distribution is closest to the population variance population sampling distribution when sample size is 30
