Question

Need help with bullet points 2 through 6 on this Intro to Probability and Statistics homework problem. All of these bullet points are part of the same problem. Make sure your handwriting is neat and readable.

 

I want to beat the traffic out of the show, so I am going to begin moving toward the exit during the encore. I decided to run some statistical tests on a data set 1 of encore durations to try to figure out when to leave (no - I'm not sharing my data). I will share the that the times were normally distributed with a sample mean of 15 and a known population standard deviation of 1. • Given that my 95% confidence interval was (14.5, 15.5), how many observations were in my data set? On my way out, Taylor told me that this is the PDF of her favorite distribution: 4x -{4₁. for 0<x</ [4(1-x) for ≤x≤1 f(x)= Unfortunately, Taylor is not sure what she can do with this function. Help a girl out. • Find the expectation. . Find the variance. • Find The CDF. • Find P{X = }}. • Find P{ ≤X ≤ }}.
