# Hypothesis Testing with One Sample

Class Time: __________________________

Name: _____________________________________

*H*: ________{0}*H*: ________{a}- In words,
**CLEARLY**state what your random variable X⎯⎯⎯ or P′ represents. - State the distribution to use for the test.
- What is the test statistic?
- What is the
*p*-value? In one or two complete sentences, explain what the*p*-value means for this problem. - Use the previous information to sketch a picture of this situation. CLEARLY, label and scale the horizontal axis and shade the region(s) corresponding to the
*p*-value.

- Indicate the correct decision (“reject” or “do not reject” the null hypothesis), the reason for it, and write an appropriate conclusion, using
**complete sentences**.- Alpha: _______
- Decision: _______
- Reason for decision: _______
- Conclusion: _______

- Construct a 95% confidence interval for the true mean or proportion. Include a sketch of the graph of the situation. Label the point estimate and the lower and upper bounds of the confidence interval.
