If the lowest value of a data set increases what happens to the standard deviation

It becomes lower

Step-by-step explanation:

This is because as the lowest value becomes larger, one of the values becomes closer to the mean, and as more numbers are closer to the mean, the standard deviation becomes lower.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

the two may have that, even a breakdown is probably offered
