As part of their work, the narrow-sense heritability for corn yield is calculated to be 0.3. If the average yield in the starting population is 400 and the breeder selects for breeding plants with an average yield of 500, what will be the expected average yield among the offspring of the selected plants? A. 530 B. 330 C. 130 D. 430 E. 230arrow_forwardSuppose that you are interested in estimating a population mean. You select a random sample of items, and compute the sample mean and the sample standard deviation. You then compute a 95% confidence interval to be LCL=28.4 - UCL=37.9. So what does that mean? It means that you are 95% confident that the unknown population mean that you are estimating is between the LCL and UCL. So what does that mean? It means that if you were to iterate this sampling process many times, say 100, and calculate 100 confidence intervals, then 95 of those intervals will contain the unknown population mean, and 5 will not.
