Answer:
This z score tell to us how many deviations we are below or above the mean for a given normal distribution.
For the case of Eddie we got:
And for the case of Sue we got:
So then for both cases we see that Eddie and Sue are 1 deviation below the true mean for each gender so then the best conclusion for this case would be:
C.They are the same size relative to other children of the same sex.
Step-by-step explanation:
We can define the random variable X as the head circumference for boys at birth and we know that the distribution for X is given by:
Similarly we can define the random variable Y as the head circumference for boys at birth and we know that the distribution for Y is given by:
And we know that Eddie was born with 33.2 cm and Sue with 32.7 cm for the head circumference . Since we are interested to determine which child's head circumference is smaller relative to other children of the same sex, we can use the z score formula given by this formula:
This z score tell to us how many deviations we are below or above the mean for a given normal distribution.

The slope of this linear equation that models the data indicate: B. the volume of helium in the balloon decreases at a rate of 0.1 cubic per minute.
<h3>What is a linear function?</h3>A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.
<h3>What is a slope?</h3>A slope is also referred to as gradient and it's typically used to describe both the ratio, direction and steepness of the function of a straight line.
<h3>How to calculate the slope of a line?</h3>Mathematically, the slope of any straight line can be calculated by using this formula;
Substituting the given points into the formula, we have;
Slope = (5 - 5.5)/(10 - 5)
Slope = -0.5/5
Slope = -0.1.
In conclusion, we can infer and logically deduce that the slope of this linear equation that models the data indicate the volume of helium in the balloon decreases at a rate of 0.1 cubic per minute.
