- 4. result of the standard deviation of a statistic is estimated from the data
- 8. an amount that is allowed for in case of miscalculation or change of circumstances
- 11. the data come from a well designed random sample or randomized experiment
- 14. statistic that provides estimate of the population

- 17. if the p-value is smaller than alpha
- 18. measure how far a sample statistic diverges from what we would expect if the null hypothesis were true
- 20. if it states that the parameter is different from the null hypothesis value
Down
- 1. is the incorrect rejection of a true null hypothesis ("a false positive")
- 2. if it states that a parameters larger than the null hypothesis value
