1.What is the Discrete Standard Deviation when sample size is 57 with a probability of 0.30?

2.What is the Central Limit Probability where x is less than 213.46 for a population mean of 207, and standard deviation of 35.19 where the sample size is 51?

3.Calculate the standard deviation products sold per store using this population data

81,0, 41,0, 32, 97

4.The claim is a mean is 98 and you want to prove it is less. Test the hypothesis using an alpha of 0.1.Your sample of 23 had a mean of 97.02 and standard deviation of 10.78. Calculate theCriticalDecisionRule.
