Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The mean weight was 3398 grams with a standard deviation of 892 grams.

This means that $\mu = 3398, \sigma = 892$

Proportion that weighed between 1614 and 5182 grams:

p-value of Z when X = 5182 subtracted by the p-value of Z when X = 1614.

X = 5182

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{5182 - 3398}{892}$

$Z = 2$

$Z = 2$ has a p-value of 0.9772

X = 1614

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{1614 - 3398}{892}$

$Z = -2$

$Z = -2$ has a p-value of 0.0228

0.9772 - 0.0228 = 0.9544.

Out of 614 babies:

0.9544*614 = 586

The number of newborns who weighed between 1614 grams and 5182 grams was of 586.

Yao Xin puts \dfrac{3}{10} 10 3 ? start fraction, 3, divided by, 10, end fraction liters of potting soil in each pot for plantin

slega [8]

Answer:

<em>She can fill 19 pots.</em>

Step-by-step explanation:

Yao Xin puts $\frac{3}{10}$ liters of potting soil in each pot.

Suppose, the number of pots Yao Xin can fill is $x$

So, <u>the total amount of potting soil</u> in $x$ number of pots will be: $\frac{3}{10}x$ liters.

Given that, she has $5\frac{2}{3} or \frac{17}{3}$ liters of potting soil. So, the equation will be........

$\frac{3}{10}x= \frac{17}{3} \\ \\ x=\frac{17}{3}* \frac{10}{3}= \frac{170}{9}=18\frac{8}{9}$

So, she can fill pots.
