... 6. Your company bids for two contracts (each of which is worth $50000 to the company). The probability you get the first contract is 0.8. If you get the first contract, the probability that you also get the second is 0.2. If you do not get the first, the probability that you get the second is 0.3. L ...

Section 10.1 ~ t Distribution for Inferences about a Mean
... When a t distribution is used to conduct a hypothesis test, the t value plays the role that the z-score played when we worked with the normal distribution Recall, that we determined statistical significance by comparing the z-score to critical values or by using the z-score to determine the Pvalue ...
