Results that are unlikely and therefore unexpected if we assume that the null hypothesis is true are called statistically significant. APPLICATION 2. ESTIMATION The biologist wants to estimate the average area used by wolf packs in North America. The researcher attaches tracking devices to the members of 7 wolf packs in North America and finds that the average area covered by the 7 wolf packs is 200 square miles. 11. In this situation, what is the population? What is the sample? 12. What variable is measured on each item in the sample? 13. The variable being measured is what type? because 14. Is the number 200 a parameter or a statistic? Explain why. A because Learning Through Practice: Statistical Reasoning1-1 Statistical Reasoning: Activity 15. If data were collected on a different set of 7 packs, we would likely get a different value than 200 since they represent a different part of the population. Statisticians calculate a margin of error to take into consideration the fact that each sample yields a different sample mean. If the margin of error were 45 mi?, then we can find an interval estimate by adding and subtracting the margin of error from the mean. a. The lower limit is the sample mean - margin of error = b. The upper limit is the sample mean + margin of error = c. The interval is written (lower limit, upper limit) = ( d. Does the interval above support the statement "wolf packs use at least 200 square miles, on average"? Why or why not? e. Does the interval above support the statement "wolf packs use at least 155 square miles, on average"? Why or why not? EXTRAS AND TIPS
