Discrete Math Functions 7. A function f: Z× Z → Z is defined as f(m,n) = 2n - 4m. Verify whether thisfunction is injective and whether it is surjective.

Here we have given a function f , we have to check, is this function injective and surjective?

Answered: A function f: Z× Z → Z is defined as…

P VALUE PLEASE In anthropological studies, an important characteristic of fossils is cranial capacity. Frequently skulls are at least partially decomposed, so it is necessary to use other characteristics to obtain information about cranial capacity. One measure that has been used is the length of the lambda-opisthion chord. An article reported the accompanying data for n = 7 Homo erectus fossils. x (chord length in mm) 78 74 78 80 83 86 87 y (capacity in cm3) 850 775 750 975 915 1,015 1,030 Suppose that from previous evidence, anthropologists had believed that for each 1 mm increase in chord length, cranial capacity would be expected to increase by 20 cm3. Do the data given here strongly contradict prior belief? Use a 0.05 level of significance. Calculate the test statistic.
