Question 14You do a study on the impact of listening to classical music in babies on IQ scores 5 yearslater, when entering elementary school. You enroll a large sample of randomly selectedfamilies in this study and the study consists of recording how long the baby listened toclassical music and their later IQ score. Doing a simple linear regression, you find that youcan strongly predict IQ scores from the hours listened to classical music. What should youdo next?a) Publish a paper on the "Mozart effect" - how listening to classical music causesbabies to be smarter.O b) Take this effect at face value, after all you did an experiment, and it is important totrust the science.c) Do a regression using socioeconomic status (SES) to predict hours listened toclassical music. Then do an additional regression using SES to predict later IQscores. Correlate the residuals of those two regressions and use that correlation inthe paper you publish.d) Do an additional regression to see if you can also predict socioeconomic status(SES) from listening to classical music.e) Unfortunately, you cannot conclude anything because of the regression to the meaneffect

We need to find the correct option regarding prediction of IQ using linear regression.

1. Suppose that a set of samples x1, x2, ..., xn, all real numbers, are drawn i.i.d. from the same distribution. Also assume that this distribution is a Gaussian distribution, which can be represented as N(u, o²). Write a function that accepts a set of samples and returns the MLE estimator for u. NOTE: The code below will be evaluated by a Python 2.7 interpreter. def mle(samples): pass Run Reset Once your function is correct, your will receive a submission code that you should input into the answer field.
