Answer 1

Answer:

if the player is a pitcher

the player has played in the Olympics

the player is an All-Star

Explanation:

Aa dummy variable or an indicator variable is a variable which attends to answer the question in yes or no, that is, which takes the value 1 for success and 0 for failure.

Here if the player is a picture can have to possible answers yes or no which takes value 1 for yes and 0 for no

Again the variable the player has played in Olympics can have two possible answers which is yes or no which takes the value 1 years and 0 for no.

Similarly the variable the player is an all star can have two possible answers Yes - the player is an all star or No - the player is not an all star, which takes the value 1 if the player is an all star and 0 if the player is not an all star.
