No the answer would be 9.

6 * 3/2 (switch it up now and do 6 * 3/2)

The average weight of a chicken egg is 2.25 ounces with a standard deviation of 0.2 ounces. You take a random sample of a dozen

n200080 [17]

Answer:

$P(\bar X$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Let X the random variable that represent interest on this case, and for this case we know the distribution for X is given by:

$X \sim N(\mu,\sigma)$

And let $\bar X$ represent the sample mean, the distribution for the sample mean is given by:

$\bar X \sim N(\mu,\frac{\sigma}{\sqrt{n}})$

On this case $\bar X \sim N(2.25,\frac{0.2}{\sqrt{12}})$

Solution to the problem

We want this probability:

$P(\bar X$

The best way to solve this problem is using the normal standard distribution and the z score given by:

$z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}$

If we apply this formula to our probability we got this:

$P(\bar X$

A rectangular area of land is being sold off in smaller pieces. The total area of the land is 2^15 square miles. The pieces bein

Nesterboy [21]

Total area of the rectangular land = 2^15 sq. miles
= 32768 sq. miles

total area of the pieces being sold = 8^3 sq. miles
= 512 sq. miles

now total no. of pieces = total area of the land / the area of samaller land that's being sold
= 32768 / 512
= 64

so the actual number of pieces is 64
