  1. A sample has SS = 50, SS = 30, SS = 16, and SS = 48.

  1. n = 7 for each of the samples, calculate the variances for each of them compute the pooled (overall) variances.
  2. What do you see regarding the position of the pooled variance?
  3. If n = 7 for the first, n = 9 and n = 4, describe the position of the pooled variance in relations to the three samples

One sample has SS = 44 and a second sample has SS = 40. Let's say that n = 8 for both samples. If we were to calculate the the two sample variances, they would be: s12 = 6.286 and s22 = 5.714. (a) Calculate the pooled variance. Because the samples are the same size, you should find that the pooled variance is exactly halfway between the two sample variances.

A sample of n = 16 individuals is selected from a population with µ = 30. After a treatment is administered to the individuals, the sample mean is found to be M = 33. We do not know the population standard deviation. A. If the sample variance is s2 = 16, then calculate the estimated standard error and determine whether the sample is sufficient to conclude that the treatment has a significant effect?

(4)(b) Using *set.seed(124)* and the Nile data, generate 1000 random samples of size n = 16, with replacement. For each sample drawn, calculate and store the sample mean. This can be done with a for-loop and use of the *sample()* function. Label the resulting 1000 mean values as "sample1". **Repeat these steps using *set.seed(127)* - a different "seed" - and samples of size n = 64.** Label these 1000 mean values as "sample2". Compute and present the means, sample standard...
