A simple random sample of 36 St Bernard dog weights yields a sample mean of 193 pounds. It is known that the standard deviation of the population of all St Bernard dog weights is 18 pounds. Suppose you suspect that an average St Bernard dog weighs less than 200 pounds and decide to test this hypothesis. For this study set-up, answer the following questions. a) Write out the research question. b) Write the null and alternative hypotheses

**d) What type of data will you collect for this study?**
*Hint: think about what sampling technique and statistic are used.*

**Suppose based on the data collected you compute your p-value.**

**e) What are the two possible results for a test on the stated hypotheses and when would you make each of those decisions?**
*Hint: think in terms of p-values.*

**f) In how many ways could you make wrong decisions while conducting a test of hypotheses in this study? What are these wrong decisions referred to as?**
*Hint: think types of errors that can be made in a hypothesis test.*
