Babies born after 40 weeks gestation have a mean length of 52.2 centimeters (about 20.6 inches). Babies born one month early hav
scZoUnD [109]

Answer:

  The standardized score (z-score), relative to all U.S. births, for a baby with a birth length of 45 centimeters is<u> 2.88cm . </u><u>   </u>                  

Step-by-step explanation:

It is given that the mean length of the babies born after the 40 weeks gestation period (\bar{x}) is 52.2cm

Standard deviation = 2.5

Baby born on one month earlier having mean length (\bar{x_2}) = 47.4cm

Now , we will use the formula for z-score ,

z =\frac{x -\bar{x_1}}{s_1}

\frac{45-52.2}{2.5}

= -2.88

<u>Therefore , A birth length of 45 centimeters is 2.88 below the mean standard deviation.</u>

So here the simpson paradox should be considered as if there is any change in weightage that lies between participation & success so we can get a contradictory view

Therefore the same would be considered
