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:

The female has a higher count relative to the sample of females than the male relative to the sample of males.

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:

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

1. Male with a count of 5.58

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

2. Female with a count of 5.23

$z-score=(5.23-4.349)/0.402=2.192$

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.

One set of markers cost x dollars. How much would set of makers and crayons cost together

inysia [295]

Answer:

x+y

Step-by-step explanation:

Let's pretend the value of the crayon's is 'y'. The value of the markers is 'x'. If we add them together, we get x+y. This is because we do not know the value of each variable.

A race is 25 miles long. There is a water station every 1 1/4 miles along the race route. How many water stations are needed for

Vikentia [17]

Answer:

Step-by-step explanation:

21 water stations

Step-by-step explanation:

From the question, we are informed that a marathon is 26.2 miles long and that there is a water station every 1 1/4miles along the race route and at the finish line.

To get the number of water stations that are needed for this marathon, we divide 26.2 miles by 1 1/4miles. This will be:

= 26.2miles/1 1/4 miles

= 26.2 miles/1.25 miles

= 20.96

= 21 water stations
