basic probability

1. Table below summarizts the distrihution of grabs in Schoods. a. What is the Fupected Value of the grader? Yea should provide both calculation and the formalas. b. With the same variable peovided it the talte for q1, peovide bedh a dintritetion as weil as the Cimmiative probubility describution. (on pager es Fxed if you preter) 2. Table below summarizes the renult of a survcy over all Tanget stores in the LS, and it peovides the number of cestomers armving at the chocken poins is Tarest saveh, as well as ihe probabiliny of each munber a. What is the averige (Expected Valuc) of the mumber ef coesoencrs amiving at the checkout point? b. Provide the destihtstion and curmalative distribution (on puger er Ercel if you prefer). 3. In the 2 data sets belive find the expected valae and Vaiasee. Then joat pruetise to thin alkout while the mean is the ame why the nagge of x and variation ia the numbers x can tabe is so different in the 29 . 4. What is as example of dictede variable and a continooes vanahle? 1. Table below sumaarises the distribution of grades in Schools. a. What is the Expected Value of the grades? You should provide both calculation and the formulas. b. With the same variable provided in the fable for ql. provide both a distribution as well as the Cumbulative probability distribution, (on paper or Exeel if you profer). 2. Table below summarixes the result of a survey over all Target siores in the US, and it poovides the number of custiomers arriving at the checkout point in Target stores, as well as the probability of each number: a. What is the average (Expected Value) of the number of cuitomers arriving at the checkoat point? b. Provide the distribution and cumalative distribution (on paper or Excel if you prefer). 3. In the 2 data sets below find the expected value and Variance. Then just promise to think about while the anean is the same why the range of x and variation in the numbers x cant take is so different in the 2%, 4. What is an example of disctete variable and a continsots variable? 1. Table below summarizts the distrihution of grabs in Schoods. a. What is the Fupected Value of the grader?
