Section 5 A regeneration survey in a recently harvested forest has indicated that 75 out of 90 plots examined were stocked (trees were growing, indicating successful regeneration). Answer the following questions (Part 1 to Part 6) using this description. Question 28 1 pts Part 1 To find the 99% confidence interval for the fraction of the total area that is stocked, which probability distribution should be used? Z distribution O F distribution O Chi-squared distribution O t distributionPart 2 To find the 99% confidence interval for the fraction of the total area that is stocked, which tabulated value do we use? Question 30 1 pts Part 3 What is the standard deviation of the proportion of total area that is stocked? Question 31 0.5 pts Part 4 Find the 99% confidence interval for the fraction of the total area that is stocked. What is the lower limit?Question 32 0.5 pts Part 5 Find the 99% condence interval for the fraction of the total area that is stocked. What is the upper limit? : ' Question 33 2 Pts Part 6 How large a sample is needed if we wish to be 95% condent that our measured proportion stocked will be within 0.05 of the true proportion? For example, the sample size could be 155. Hint: Write a whole number. E
