Answer:
Option D) The number of standard deviations a measurement is from the mean
Step-by-step explanation:
Standard Score:
- Standard score is also known as the z-score, z-value, normal scores or the standardized score.
- It tells us about the values of standard deviations by which the value of data point is above or below the mean value.
- The standard score for a data point may be negative or positive.
- It is obtained by subtracting the population mean from the data point and then dividing it by the population standard deviation.
- It is known as standardization or normalization.
Thus, standard score can be defined as:
Option D) The number of standard deviations a measurement is from the mean
The probability that he will pull out a nickel, then a quarter, then a nickel is
<u>Explanation:</u>
Given:
Number of dimes = 3
Number of Quarters = 2
Number of pennies = 2
Number of Nickles = 5
Total coins = 3 + 2 + 2 + 5
= 12
Probability that Armando will pull out Nickel first =
After taking out Nickel, the total number of coins in the pocket will be 11
So,
Probability that he will pull a quarter =
Total coins remaining = 11 - 1 = 10
Total Nickel remaining = 5 - 1 = 4
Probability that he will take our Nickel =
Total probability =
=
