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: f (x) = for 0 < x < for<r <1 4(1-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 ≤}}.
