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?

Question

Need help with this Intro to Probability and Statistics homework 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:
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 ≤}}.
