Males have red blood cell counts with a mean of 4.719 and a standard deviation of .490, while females have red blood cell counts
iVinArrow [24]

Answer:

  • <em><u>The female  has a higher count relative to the sample of females than the male relative to the sample of males.</u></em>

Explanation:

When you want to compare the means of two samples with different statistics you may use the z-score.

The z-score measures how far a value (data point) is from the mean, in terms of the standard deviation.

The z-score is calculated as:

          z-score=(x-\mu )}/\sigma

Where:

          x=\text{value of the data}\\\\\mu =mean\\\\\sigma = \text{standard deviation}

<u>1. Male with a count of 5.58 </u>

       z-score=(5.58-4.719)/0.490=1.757

<u />

<u>2. Female with a count of 5.23</u>

     z-score=(5.23-4.349)/0.402=2.192

Therefor, the z-score of the female is greater than the z-score of the male.

The greater z-score means that, relative to her group, the female has a higher count than the male.

Two angles are supplementary. The larger angle is 15 more than 10 times the smaller angle. FInd the measure of each angle.
garik1379 [7]

\text{Larger angle} =x\\\\\text{Smaller angle} =y\\ \\\text{According to the condition,}\\\\x=10y+15\\\\\text{The two angles are supplementary, so their  sum is}~ 180^{\circ} \\\\x+y=180\\\\\implies 10y+15 +y = 180\\\\\implies 11y = 180-15\\\\\implies 11y=165\\\\\implies y = \dfrac{165}{11}\\\\\implies y = 15\\\\\text{So,} ~x  =180-15 = 165\\\\\text{Hence the larger angle is}~ 165^{\circ}~ \text{and the smaller angle is }15^{\circ}
