2. Whether you have had a course on statistics or not, you are likely to have heard of the normal (or bell) curve. This is what is referred to in statistics as a probability distribution which are used to calculate probabilities. In particular the normal distribution is defined by the probability density function, with mean = 0 and standard deviation = 1. f(x) = -√² (Take a moment and graph this function to see why it's referred to as a 'bell curve'.) Using functions such as these, we may calculate probabilities by simply calculating the area under the graph of this function. For example, it can be shown that AL e-²²dr = 1 which can be interpretted as the probability of a value falling between -∞o and ∞o, in a normally distributed set of data, is 1 (or 100% probability). We'll now calculate the probability that a student's exam score falls within one standard deviation from the overall average. (In other words, with some scaling, the probability of scoring ±10 from 75 if the exam scores fit a standard bell curve) (a) Using a known Maclaurin series, find a series representation centered at c = 0 for f(x) = -¹² (b) (c) Integrate the series you found to compute Put your answer in sigma notation. Lete de Find an approximation to this sum with accuracy < 0.00005.
