The brain volumes (cm^3) of 20 brains have a mean of 1175.5 cm^3 and a standard deviation of 124.6 cm^3. use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly high. for such data, would a brain volume of 1444.7 cm^3 be significantly high?

there are no choices to this, can you give us some choices so that i can answer it

step-by-step explanation:

wait this depends wether emily and zach how they are thinking.

yes they are the same.

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
