Problem 5 (

Problem 5 10 min) A 2021 study compared the spring and autumn migratbn of Swan Geese, a threatened bird species found in East Asia. A random sample of 81 Swan Geese were fitted with GPS collars, allowing the researchers to record how long (in days) each bird had taken to complete the whole migration in the spring and the retum trip in tte fall Cautumn"). Here is a quote from the published study The geese took an average of 64.115.4 days to complete their autumn southboulki migration, and 29.76.2 days to complete the retum northboulki migration. The migration duration of spring migration was significantly shorter than autumn migration (df=80, 19.0, P < 0.001). a) What is the null hypothesis corresponding to the reported P-value?
