Which of these numbers of simulations of an event would be most likely to produce results that are closest to those predicted by
LuckyWell [14K]
<span>C. 80 simulations would be the most likely to reproduce results predicted by probability theory. Due to the law of large numbers, as the number of trials increase, the actual ratio of outcomes will converge on the theoretical, or expected, ratio of outcomes.</span>

What does it mean when the ratio of person 1’s income to person 2’s incomes is 1 to 3 or 3 to 1? Explain.
viktelen [127]

Answer with explanation:

3:1 means that person 1's income is three times person 2's income.

E.g.: if person 1 gets 150 per hour, person 2 gets 30 per hour.

1:3 means that person 1's income is one third of person 2's income.

E.g.: if person 1 gets 40 per hour, person 2 gets 120 per hour.

Raju’s father’s age is 5 years more than three times Raju’s age. Find Raju’s age,
Harrizon [31]

Answer:

Step-by-step explanation:

In order to find the answer, let's work backwards to find the original. We have to do the opposite to get to the Raju's age. We will start with his fathers age. (44) Then we will subtract five from it so that it will be divisible by three.

44 - 5 = 39

Then we just have to divide by 3.

44/3 = 13

His age is 13 years old.

Due to normality, the formula for computing z is the same for a single data value, as it is
katrin2010 [14]

Using the <u>Central Limit Theorem</u>, the statement is false, as for the averages of  the data values for a sample group, the standard error is s = \frac{\sigma}{\sqrt{n}}, hence, the formula is:

Z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

While for a single value, it is:

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

In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:

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

  • It 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, which is the percentile of X.
  • By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation s = \frac{\sigma}{\sqrt{n}}.

Hence, the formulas are different, and for an average of the data values for a sample group it is:

Z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}
