Newborn males have weights with a mean of 3272.8 g and a standard deviation of 660.2 g. Newborn females have weights with a mean

Maksim231197 [3]

The correct option is: a female who weighs 1500 g

<em><u>Explanation</u></em>

<u>Formula for finding the z-score</u> is: $z= \frac{X-\mu}{\sigma}$

Newborn males have weights with a mean $(\mu)$ of 3272.8 g and a standard deviation $(\sigma)$ of 660.2 g.

So, the z-score for the newborn male who weighs 1500 g will be.......

$z(X=1500)=\frac{1500-3272.8}{660.2}=-2.685... \approx -2.69$

According to the normal distribution table, $P(z=-2.69)=0.0036 = 0.36\%$

Now, newborn females have weights with a mean $(\mu)$ of 3037.1 g and a standard deviation $(\sigma)$ of 706.3 g.

So, the z-score for the newborn female who weighs 1500 g will be.......

$z(X=1500)=\frac{1500-3037.1}{706.3}=-2.176... \approx -2.18$

According to the normal distribution table, $P(z=-2.18)=0.0146 = 1.46\%$

As we can see that the <u>probability that a newborn female has weight of 1500 g is greater than newborn male</u>, so a newborn female has the weight of 1500 g that is more extreme relative to the group from which he came.

7800 nm + 95 pm in scientific notation

azamat

$7800 nm+95pm=7800* 10^{-9} +95* 10^{-12}$
$=7800000* x^{-12} +95* 10^{-12} =7800095* 10^{-12} =7.800095* 10^{-6}$

The variable z is directly proportional to x. When x is 6, z has the value 60. What is the value of z when x = 11?

user100 [1]

Answer:

110

Step-by-step explanation:

z is apparently 10 times x.

10 times 11 is 110.

The troposphere extends from the Earth's surface to a height of 6–12 miles, depending on the location and the season. If a plane

Anni [7]

Answer:

2.8 miles higher the plane go without leaving the troposphere?

Step-by-step explanation:

Troposphere height on different locations= 6-12 miles

plane altitude at present flight = 5.8 miles.

Troposphere deepness from the present flight= 8.6 miles

So from present altitude till troposphere= 8.6-5.8= 2.8 miles
