population mean. (B) The average sample mean‚ over all possible samples‚ equals the population mean. (C) The sample mean is always very close to the population mean. (D) The sample mean will only vary a little from the population mean. A2. The central limit theorem tells us that the sampling distribution of the mean is approximately normal. Which of the following conditions are necessary for the theorem to be valid? (A) The sample size has to be large. (B) We have to be sampling from a normal population

Comment on the forecasting system being used by Yankee. What would be the smoothing forecast for Yankee for Month 1 of Year 5 using the four Month 1 data points in each of the last 4 years using an alpha of .3. (the demand for Month 1 of year 1 is the most historical data point.) Do this manually setting the very first forecast equal to the very first demand value)

Abstract According to Mendel¡¦s Law of Segregation‚ phenotypic ratios may be influenced by dominance of one allele compared to another. When an organism produces its gametes by meiosis‚ the alleles separate. This is Mendel¡¦s First Law-the Law of Segregation. This experiment investigated the effects of complete and incomplete dominance on the behavior of two different genes for chlorophyll production in tobacco. Two sets of approximately 50-100 tobacco seeds were planted for one week. The plants

Chapter 14 14.3. Explain the principle of risk-neutral valuation. The price of an option or other derivative when expressed in terms of the price of the underlying stock is independent of risk preferences. Options therefore have the same value in a risk-neutral world as they do in the real world. We may therefore assume that the world is risk neutral for the purposes of valuing options. This simplifies the analysis. In a risk-neutral world all securities have an expected return equal to risk-free

to contain the parameter‚ known as confidence intervals. The width of the confidence interval gives us some idea about how uncertain we are about the unknown parameter. The narrower the range of the confidence interval the more accurate the estimate will be. 1b The central limit theorem‚ ‘whatever the distribution of the population‚ the mean of a large sample has an (approximate) normal distribution’. (Swift and Pitt p 498). The calculation of the confidence interval is therefore based on a standardised
