The brain volumes (cm³) of 20 brains have a mean of 1147.7 cm³ and a standard deviation of 120.8 cm³. Use the given standard deviation in the range rule of thumb to identify the limit separating values that are significantly hot low or significantly high. For such data what a brain volume of 1349.3 cm³ Be significantly high?

fill the blank.

1. Significantly low values are __ cm³ or lower.

2. Significantly high values are __ cm³ or higher.

choose from the choices below.

is 1349.3 cm³ significantly high?

a. yes because it is below the lower limit separating value

b. Yes because it is between the limit separating values.

c. Yes because it is above the upper limit seperating value

d. No because it is above the upper limit separating value. e. No because it is below the lower limit separating value.

f. No because it is between the limits seperating value.
