Standard errors of the means
WebbThe standard error is calculated using the standard deviation and the sample size: se ( y) = s y / n. Therefore, for our female heights sample, the standard error was calculated as se ( y) = 6.89 / 1000 ≈ 0.22 cm. Notice that with greater n, the standard error will be smaller. Webbg denote the set of sampled observations that belong to the gth standard stratum and define I D g (j) to indicate if the jth observation is a member of the gth standard stratum; where g= 1;:::; L D and L D is the number of standard strata. Also, let ˇ g denote the fraction of the population that belongs to the gth standard stratum, thus ˇ 1 ...

You get ∞ on your TI-83 as 1 [ 2nd , makes EE] 99, or as 10^99. Caution: invNorm works from area to left. If the problem actually gives you an area to the right or an area in the middle, you ... WebbThe mean is the average of the observations in the data set. To calculate the mean, we add up all the observations and divide by the total number of observations. For male subjects, the sum of all observations is 113, and there are 20 observations. Therefore, the mean is 113/20 = 5.65 (rounded to the nearest hundredth).
