- Use the One Proportion applet to create a null distribution and find a p-value. Paste ascreenshot as part of your solution that shows the null distribution, the p-value, and everything you entered in the applet.
- State the strength of evidence against the null hypothesis based on the p-value and interpret the p-value in this context (i.e., the probability of what, assuming what?).
- Calculate the standardized statistic (show your work) and give the correct symbol for this value. State the strength of evidence against the null hypothesis based on the standardized statistic.
- Interpret the standardized statistic.
