A scientist uses a submarine to study ocean life. • She begins at sea level, which is an elevation of o feet.
She travels down 31.6 feet.

How many feet must she now ascend to get back to sea level?

Scores on the cognitive scale of the bayley-scales of infant and toddler development range from 1 to 19, with a standard deviation of 3. calculate the margin of error in estimating the true mean cognitive scale score, with 99% confidence, if there are 12 infants and toddlers in a sample.
