The average duration or labor from the first contraction to the bim of the baby in women over 35 who have not previously given brth and who did not use any pharmaceuticals is 26 hours. Suppose you have a sample of 33 women who exercise daly, and who have an average duration of labor of 16.9 hours and a sampie variance of 20.3 hours. You want to test the hypothesis that women who exercise daly have a omerent duration of labor than all women. Calculate the t statistic To do this, you first nend to calculate the estimated standard emor. The estimated standard emor is s- statistie is The t Now suppose you have a larger sample sizen-81. Calculate the estimated standard emror and the t statistic for this sample wth the same sample average and the same standard deviation as above, but with the larger sample sze.

The average duration of labor from the first contraction to the birth of the baby in women over 35 who have not previously given birth and who did nat t use any pharmaceuticals is 16 hours. Suppose you have a sample of 33 women who exercise daily, and who have an average duration of labor of 16.9 hours and a sample variance of 20.3 hours. You want to test the hypothesis that women who exercise daily have a different duration of labor than all women. Calculate thet statistic. To do this, you first need to calculate the estimated standard error. The estimated standard error is sy - ▼ . The t statistic is ▼ Now suppose you have a larger sample size n- 81. Calculate the estimated standard error and thet statistic for this sample with the same sample average and the same standard deviation as above, but with the larger sample size. The new estimated standard error is Y. The new t statistic isv Note that the t statistic becomes as n becomes larger. Use the Distributions tool to look at the t distributions for different sample sizes. To do this, choose the Degrees of Freedom for the first sample size on s the slider, and click the radio button with the single orange line. Move the orange vertical line to the right until the number below the orange line is located on the t statistic.
