it is traditionally believed in the literature on bird migration that godwits that migrate between Alaska and New Zealand travel a mean distance of 11,125 km non-stop. The past several years, more godwits than usual have been observed breeding in the southernmost regions of Alaska. Because of this, a researcher claims the godwits are now traveling a shorter mean distance non-stop. To test this claim, he studied 21 randomly chosen godwits that migrated between Alas and New Zealand. The birds traveled a sample mean distance of 11,045 km non-stop with a sample standard deviation of 345 km. Assume that the population of distances traveled non-stop between Alaska and New Zealand by godwits is approximately normally distributed. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to support that u, the mean distanc godwits travel non-stop between Alaska and New Zealand, is now less than 11,125 km. (a) State the null hypothesis H, and the alternative hypothesis H, that you would use for the test. Ho: I H: I OSO 口と回口=口
