Cell Phone Consumption The number of UC Merced students (Y, in thousands) who need X smart phones during their time at UC Merced can be loosely modeled by the Pareto distribution with PDF f(x) = (a) What is the shape parameter a?
(b) Compute the expected number of cell phones and the standard deviation.
(c) Build the "range rule of thumb" interval (4 – 20,4 +20)
(d) If a student goes through 3 cell phones during their time at UC Merced, is that amount of cell phones unusual?

How many lines can be drawn through points j and k? 0 1 2 3

The perimeter of an equilateral triangle is 4 cm more than the perimeter of a square and the length of a side of the triangle is 8 cm more than the length of a side of the aware. find the length of a side of the equilateral triangle

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. what can you conclude? 2(0.21) = 0.42 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. 0.21 > 0.05; the test is statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time, so the test is not statistically significant. p = 1 - 0.21 = 0.79 > 0.05; the test is statistically significant.
