Hello, I have the following mixed exponential distribution formula: 34/99*0.5e^(-0.5y) + 328/99*0.25e^(-0.25y) where y < 0 is zero I need to calculate mean, variance and quartiles. But the problem is, because it is mixed and does not integrate to 1. How can I calculate those?

Question

Hello, I have the following mixed exponential distribution formula:

34/99*0.5e^(-0.5y) + 328/99*0.25e^(-0.25y)

where y < 0 is zero

I need to calculate mean, variance and quartiles. But the problem is, because it is mixed and does not integrate to 1. How can I calculate those?

With differentiation, one of the major concepts of calculus. Integration involves the calculation of an integral, which is useful to find many quantities such as areas, volumes, and displacement.

26) Below is some of the regression output from a simple regression of the number of wins for a major league baseball team and the size amount of money the team is paying its players (expressed in millions of $'s) *fill in the blank table* Suppose that the team owner is trying to decide whether to pay a particular free agent player. Based on the player's previous statistics, the owner thinks that the new player can help his team increase the number of wins but the new player is going to cost more than the player he will be replacing. The owner decides it is a good idea to sign the new player if he can be pretty sure that the coefficient is at least 0.20. When testing this hypothesis, what is the test statistic?
