Or might the result be due to confounding? Explain.Do these data provide good evidence that increasing the stiring rate causes the yield toincrease, within the range of the data? Or might the result be due to confounding?Explain.Б.C.d. Which experimental design is better, this one or the one in Exercise 7? Explain.

Prof. Reed is interested in studying the determinants of fertility. She believes that women who report that they would like to have a higher number of children will actually have a higher fertility than women with low fertility ideals. The results from her analysis are based on the 2002 GSS. Calculate how much a woman's ideal fertility contributes to predict the variance of her actual number of children? Std. Mean Deviation Number of children 1.65 1.451 Ideal number of children 2.95 1.805 Pearson's r .144 Number of cases 211
A scientist wants to develop a model to describe the relationship between the average daily temperature, x °C, and her household’s daily energy consumption, y kWh, in winter. A random sample of the average daily temperature and her household’s daily energy consumption are taken from 10 winter days and shown in the table. x -0.4 -0.2 0.3 0.8 1.1 1.4 1.8 2.1 2.5 2.6 y 28 30 26 25 26 27 26 24 22 21 You may use: Sy=255 Sxy=283.8 Syy= 64.5 Find a value for the product moment correlation coefficient r for this data Explain what the value of the product moment corelation tells you about the relationship between daily temperature and the household energy consumption.
A solar panel store manager suspects that his inventory levels of solar panels have been higher than necessary. Based on the record of the number of solar panels held in inventory each day during the last sixty days, the manager came up with the following distribution. # of Solar Panels Frequency 15 15 16 14 17 10 18 19 20 The demand for the solar panels follows a normal distribution with u=17 and 6=2. Based on this information, 1. Develop a Monte Carlo Simulation model on MS Excel of this situation (send me a copy of tie model.) 2. Based on one thousand iterations, should the manager change the inventory policy for the solar panels? (answer in the available space below.)

Inorganic phosphorous is a naturally occurring element in all plants and animals, with concentrations increasing progressively up the food chain (fruit < vegetables < cereals < nuts < corpse). Geochemical surveys take soil samples to determine phosphorous content (in ppm, parts per million). A high phosphorous content may or may not indicate an ancient burial site, food storage site, or even a garbage dump. Independent random samples from two regions gave the following phosphorous measurements (in ppm). Assume the distribution of phosphorous is mound-shaped and symmetric for these two regions.
