Lecture 2. Introduction to Probability

1. 1 The p-value, which we use in inferential statistics is an [blank_start]actual[blank_end] [blank_start]probability[blank_end] [blank_start]value[blank_end]

   1. Aactual
   2. Bprobability
   3. Cvalue
2. 2What is probability?

   1. AThe number of specific events occurring divided by all possible events.
   2. BThe number of all possible events divided by the number of specific events
3. 3Probability ranges from 0 to 10

   1. AVerdadero
   2. BFalso
4. 4The probability that an event WILL NOT occur is known as the [blank_start]complement[blank_end]

   1. Acomplement
5. 5The [blank_start]addition rule[blank_end] is used to find the probability of two mutually exclusive events, however the [blank_start]multiplication rule[blank_end] is used to fine the probability of two independent events

   1. Aaddition rule
   2. Bmultiplication rule
   3. Cmultiplication rule
   4. Daddition rule
6. 6Another name for the multiplication rule is the [blank_start]joint[blank_end] [blank_start]probability[blank_end] rule

   1. Ajoint
   2. Bprobability
7. 7When should you use the modified multiplication rule?

   1. AWhen the events are independent and you want to find the probability that either event occurs
   2. BWhen the events are non-independent and you want to find the probability that either event occurs
   3. CWhen the events are independent and you want to find the probability that both occurs together
   4. DWhen the events are non-independent and you want to find the probability that both occurs together
8. 8When would you use the modified addition rule?

   1. AWhen the events are mutually exclusive and you want to find the probability that either event occurs.
   2. BWhen the events are mutually exclusive and you want to find the probability that both events occur.
   3. CWhen the events are non-mutually exclusive and you want to find the probability that either event occurs.
   4. DWhen the events are mutually exclusive and you want to find the probability that both events occur
9. 9Which probability rule would you use find the probability that a person has Type A blood OR Type O blood?

   1. AAddition rule
   2. BMultiplication rule
   3. CModified Addition rule
   4. DModified Multiplication rule
10. 10Which probability rule would you use to find the probability that a person is male OR has type O blood?

    1. AAddition rule
    2. BMultiplication rule
    3. CModified addition rule
    4. DModified multiplication rule

11. 11Which probability rule would you use to find the probability that a person is male AND has type O blood?

    1. AAddition rule
    2. BMultiplication rule
    3. CModified addition rule
    4. DModified multiplication rule
12. 12What probability rule would you use if you wanted to find the probability that you passed the NAPLEX AND became a pharmacist?

    1. AAddition rule
    2. BMultiplication rule
    3. CModified addition rule
    4. DModified multiplication rule
13. 13If the p-value is less than [blank_start]0.05[blank_end] then the results are statistically significant

    1. A0.05
14. 14Alpha is a probability threshold is is equal to 0.05.

    1. AVerdadero
    2. BFalso
