$\qquad \tt \rightarrow \: f(0) = -3$

$\qquad \tt \rightarrow \: f(2) = 1$

$\qquad \tt \rightarrow \: f(4) = 1$

____________________________________

$\large \tt Solution \: :$

F(x) represents the value of y on curve for given value of x

$\textsf{\large First -}$

$\qquad \tt \rightarrow \: f(0) =( 0) {}^{2} - 3$

[ since 0 < 2 ]

$\qquad \tt \rightarrow \: f(0) = 0 {}^{} - 3$

$\qquad \tt \rightarrow \: f(0) = - 3$

$\textsf{\large Second}$

$\qquad \tt \rightarrow \: f(2) = (2) {}^{2} - 3$

[ since 2 = 2 ]

$\qquad \tt \rightarrow \: f(2) = 4{}^{} - 3$

$\qquad \tt \rightarrow \: f(2) = 1$

$\textsf{\large Third -}$

$\qquad \tt \rightarrow \: f(4) = - 4 + 5$

[ since 4 > 2 ]

$\qquad \tt \rightarrow \: f(4) = 1$

A study conducted by the Center for Population Economics at the University of Chicago studied the birth weights of 623 babies bo

Margaret [11]

Answer:

The estimation for the number of newborns who weighed between 1724 grams and 5172 grams is 595.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 3448, \sigma = 862$

Proportion of newborns who weighed between 1724 grams and 5172 grams.

This is the pvalue of Z when X = 5172 subtracted by the pvalue of Z when X = 1724. So

X = 5172

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

By the Central Limit Theorem

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

$Z = \frac{5172 - 3448}{862}$

$Z = 2$

$Z = 2$ has a pvalue of 0.9772

X = 1724

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

$Z = \frac{1724 - 3448}{862}$

$Z = -2$

$Z = -2$ has a pvalue of 0.0228

0.9772 - 0.0228 = 0.9544

Estimate the number of newborns who weighed between 1724 grams and 5172 grams.

0.9544 out of 623 babies. SO

0.9544*623 = 595

The estimation for the number of newborns who weighed between 1724 grams and 5172 grams is 595.
