A puck company wants to sponsor the players with the 10% quickest goals in hockey games. The times of first goals are normally distributed with a mean of 8.54 minutes and a standard deviation of 4.91 minutes. How fast would a player need to make a goal to be sponsored by the puck company?

And if we solve for a we got

And for this case we can conclude that the time required needs to be 2.2552 minutes or less in order to be sponsored

Step-by-step explanation:

Let X the random variable that represent the time for goals in hockey games of a population, and for this case we know the distribution for X is given by:

Where and

For this part we want to find a value a, such that we satisfy this condition:

  (a)

  (b)

As we can see on the figure attached the z value that satisfy the condition with 0.10 of the area on the left and 0.90 of the area on the right it's z=-1.28.

If we use condition (b) from previous we have this:

and we can do the following

And if we solve for a we got

And for this case we can conclude that the time required needs to be 2.2552 minutes or less in order to be sponsored
