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.

The closing price of Schnur Sporting Goods Inc. common stock is uniformly distributed between $16 and $30 per share.

serg [7]

Answer:

a) 0.3571 = 35.71% probability that the stock price will be more than $25.

b) 0.1429 = 14.29% probability that the stock price will be less than or equal to $18.

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.

The probability of finding a value of at lower than x is:

$P(X < x) = \frac{x - a}{b - a}$

The probability of finding a value between c and d is:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

The probability of finding a value above x is:

$P(X > x) = \frac{b - x}{b - a}$

Uniformly distributed between $16 and $30 per share.

This means that $a = 16, b = 30$

a) More than $25?

$P(X > x) = \frac{30 - 25}{30 - 16} = 0.3571$

0.3571 = 35.71% probability that the stock price will be more than $25.

b) Less than or equal to $18?

$P(X < 18) = \frac{18 - 16}{30 - 16} = 0.1429$

0.1429 = 14.29% probability that the stock price will be less than or equal to $18.
