The population standard deviation σ of a discrete random variable ‚ Measure how close a random variable tends to be the population mean μ‚ so you must understand μ before you understand σ If you have a random variable like a bet at a casino or and investment then the standard deviation σ measure the risk‚ if there is a lot of risk then the standard deviation is high The formulas for standard deviation are given below but you should look at the examples first Population mean Population variance

I also chose to break this norm because I own a horse mask‚ but have not figured out the perfect moment to wear it. The norm breaking

regularly consumes a special type of glue purchased from a foreign supplier. Because the supplier is foreign‚ the time gap between placing an order and receiving the shipment against that order is long and uncertain. This time gap is called “lead time.” From past experience‚ the materials manager notes that the company’s demand for glue during the uncertain lead time is normally distributed with a mean of 187.6 gallons and a standard deviation of 12.4 gallons. The company follows a policy of placing
