In a normal distribution, the mean has Standard Score: z =
Using the normal distribution, it is found that the z-scores are:
1) z = -0.8
2) z = 2.4
3) z = 0
In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:
Item 1:
0.8 standard deviations below the mean, hence z = -0.8.
Item 2:
2.4 standard deviations above the mean, hence z = 2.4.
Item 3:
The mean is 0 standard deviations from itself, hence z = 0.

A standard score (z-score) signifies how many standard deviations a data point is away from the mean. A data value 0.8 standard deviations below the mean has a z-score of -0.8, meanwhile, if it is 2.4 standard deviations above the mean, its z-score is 2.4. The mean in a normal distribution has a z-score of 0.
In the field of statistics, a standard score (also known as a z-score) represents how many standard deviations an element is from the mean. In a normal distribution, a data value located 0.8 standard deviations below the mean has a Standard Score: z = -0.8. This is because the z-score is negative when the data value is below the mean. Conversely, a data value located 2.4 standard deviations above the mean has a Standard Score: z = 2.4. As the data value is above the mean, the z-score is positive. Finally, for the mean value itself in a normal distribution, the Standard Score: z = 0 because the mean value is the center of distribution, hence no deviation from itself.

Answer:
15 yards of ribbon does olivia need for 18 balloons
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity 1 such as 4 meter per seconds or 5 miles per hours.
As pert the statement:
Olivia ties 2.5 feet of ribbon onto one balloon.
⇒ ft ribbon
Use conversion:
1 feet = 1/3 yard
then;
2.5 ft = 0.833333333 yard
⇒ yard ribbon
We have top find how many yards of ribbon does olivia need for 18 balloons
Substitute the given values we have;
yards
Therefore, 15 yards of ribbon does olivia need for 18 balloons
