The brain volumes (cm³) of 20 brains have a mean of 1106.7 cm³ and a standard deviation of 126.2 cm³. Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of 1309.1 cm³ be significantly high? Significantly low values are (Type an integer or a decimal. cm³ or lower. Do not round.) Significantly high values are cm³ or higher. (Type an integer or a decimal. Do not round.) Is 1309.1 cm³ significantly high? OA. Yes, because it is below the lower limit separating value. B. No, because it is above the upper limit separating value. OC. Yes, because it is between the limits separating values. O D. No, because it is between the limits separating values. OE. Yes, because it is above the upper limit separating value. OF. No, because it is below the lower limit separating value. ~
Use z scores to compare the given values. Based on sample data, newborn males have weights with a mean of 3234.3 g and a standard deviation of 544.6 g. Newborn females have weights with a mean of 3036.7 g and a standard deviation of 598.7 g. Who has the weight that is more extreme relative to the group from which they came: a male who weighs 1700 g or a female who weighs 1700 g? Since the z score for the male is z=nothing and the z score for the female is z=nothing, the ▼ male female has the weight that is more extreme. (Round to two decimal places.)
