• Assume a = 0.05 unless otherwise noted. • Show your work and include appropriate units with answers when relevant. Round all numeric answers to at least 3 decimal places. ● Mourning doves create nests in a wide range of sizes. Researchers want to know if nest size impacts the size of the eggs the birds lay, so they collect one randomly-chosen egg from each of 40 unrelated nesting doves. After confirming all relevant assumptions, they calculated the following: Mean Std. Dev. Nest Area (cm²) Egg Length (mm) 31.75 8.20 4.19 0.38 r = 0.47 a. Calculate the 95% confidence interval for the correlation between nest area and egg length. Given: critical value = 2.02 b. Calculate the estimated linear regression equation for this analysis and write the full equation Then interpret each estimate in context
