A recent study found that in a sample of 300 smooth hair dachshunds, 72 of the dogs developed Intervertebral Disc Disease (IVDD).In a separate sample of 250 wire-haired dachshunds, 18 of the dogs developed Intervertebral Disc Disease (IVDD).Is the sampling distribution for the difference of proportions between the breeds of dogs that develop IVDD approximately normal?Why?Show your work.
