Question
- You may NOT use any Python packages other than random, math and copy Use your pseudorandom number generator to generate a list of 1000 uniformly-distributed, random, floating-point numbers between 0 and 1 (duplicates are okay). Consider these values to represent probability levels pi that can be found by integrating the Gaussian probability density function (PDF) between
x=μ-5⋅σ to x=xi such that pi=P(x<xi|N(μ,σ)) where μ=175, σ=15.
- Using your Simpson function (nPoints=50) to integrate the Gaussian PDF combined with your Secant method for root finding, find the set of x values compatible with your list of 1000 probabilities. Note: you will need to use callback functions for this process.
- Finally, calculate the estimates of the population parameters μ and σ2 using the unbiased sample estimators from your set of x values. Compare your values to those from N(175, 15).
Output the values for your population estimators like:
Population mean estimate = y.yy
Population variance estimate = z.zz
Note: you may need to use a clamp function to confine your probabilities to fall within the lower limit associated with the lower limit for integration.
(i.e., make sure pi≥P(x≤μ-5⋅σ|N(μ,σ))=Simpson(GPDF, (μ, σ), μ-10*σ, μ-5*σ))
