Here I got another stadistics problem to solve. Thanks!

Consider the demand at a store given by the data in the previous question, i.e., the demand at a store that can be modeled by a random variable with values and corresponding probabilities shown in 02. Which of the following statements about the standard deviation of the demand distribution is true? The standard deviation cannot be calculated for this data. The standard deviation is greater than or equal to 0 but less than 10. The standard deviation is greater than or equal to 20 but less than 30. The standard deviation is greater than or equal to 30 but less than 40. 00000 The standard deviation is greater than or equal to 10 but less than 20
