d.5 pounds

Answer 1

Your answer is most likely B
one ounce is too small
five pounds is too large
and four pounds seems like it wouldn't be accurate enough

Answer 2

Answer: b. 1 pound

Explanation:

Given: Local hospital is making a histogram of the birth weight of babies born in the past year. there were 1023 babies born in the hospital last year. the weights range from 4 lb to 11 lb.

They should use 1 pound scale on the x-axis, which makes easier to to study the histogram. .

because from the given options 1 ounce is one sixteenth of a pound i.e. too small.

4 pounds scale will make total intervals =3 , which will make more difficult to study the histogram.

5 pounds scale is larger than 4 pounds scale, thus it can not be the rquired scale.
