Question

he mean weight of a baby girl is 7.05 pounds with a standard deviation of 0.88 pounds if 932 babies were born at a particular hospital in 2012 how many of them weighed less than 6.25 pounds @whpalmer4

Answer 1

Undoubtedly there's a formula you could use to figure out how many babies fall under the curve to the left of 6.25 pounds, but I'm not really a statistics weenie. I do wonder if perhaps the standard deviation isn't supposed to be 0.8 pounds instead of 0.88 pounds, which would make this be exactly 1 standard deviation below the mean, and there is a rule of thumb that would allow you to easily get the answer if that is the case...

Answer 2

it says 0.88 on the paper so it cant be done using the information i provided theres something else to it
