Add together all the numbers with the common variable leaving the constant at the end.
13t+12=64
Subtract 12 from both sides.
13t=52
Finally, divide by 13 to isolate the variable.
t=4

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.
