The table shows the results of a study investigating whether aftereffects of epidurals administered during childbirth might intefere with successful breastfeeding. We're Breastfeeding planning to do a chi-square test. Complete parts a through c. Yes 205 183 388 Epidural? No 493 278 Total 698 461 1159 Yes 0 Total at 6 months? a) How many degrees of freedom are there? b) The smallest expected count will be in the epidural / no breastfeeding cell. What is it? (Round to two decimal places as needed.) c) Check the assumptions and conditions for inference. Select all the assumptions and conditions that the problem satisfies. A. Independence assumption: The babies are independent of each other. 10% condition: The 1159 babies are less than 10% of all babies . C. Counted data condition: The data are given as counts D. Randomization condition: The babies are representative E. Expected cell frequency condition: The expected values are all at least 5.
