Did the number of times that a female mated affect her proba

Did the number of times that a female mated affect her probability of giving birth?

a) Calculate expected frequencies for a contingency test.

b)Examine the expected frequencies. Do they meet the assumptions of the chi2 contingency test? If not, what steps could you take to meet the assumptions and make a test?

c)An appropriate test shows that the number of mates of the female prairie dogs is associated with giving birth. Does this mean that mating with more males increases the probability of giving birth? Can you think of an alternative explanation??

Number of times female mated: Number who gave birth: Number who didn\'t give birth: 6 1 2 81 85 61 17 5 8 0 0 0
