According to Forbes, the average age of millionaires in the US 10 years ago was 62 years old. Since
then, the number of millionaires in the US has grown to over 17 million. One prevalent belief among
economists is that the average age of millionaires today has decreased from the average age of
millionaires 10 years ago. To investigate this belief, a random sample of 50 millionaires from the US was
selected and their ages were recorded. Here are the summary statistics.

Based on this sample, is there convincing evidence that the true mean age of millionaires in the US is
less than 62 years old? Use a = 0.01. Provide statistical evidence to support your answer.
In the sample, there is convincing evidence that the true mean age of millionaires in the US is less than 62 years old
How to illustrate the sample?From the information given, the sample mean is 51 and the standard deviation is 10.2. The sample is 50 and the level of significance is 0.01.
The test statistic will be:
= (51 - 62)/(10.20/✓50)
= -7.63
The degree of freedom will be:
= n - 1
= 50 - 1
= 49
Since the p-value is less than 0.05, we will reject the null hypothesis. Therefore, there is a convincing evidence that the true mean age of millionaires in the US is less than 62 years old

Answer:
Sample mean = x = 51
Sample standard deviation = s = 10.2
Sample size = n = 50
Level of significance = a = 0.05
Null and Alternative Hypotheses:
0: μ= 62
а: μ< 62
This corresponds to a left-tail test, for which a t-test for one mean, with unknown population standard deviation will be used.
Test statistic:
t = x - μ / (s / sqrt n)
t = 51 - 62 / (10.20 / sqrt 50)
t = -7.63
Test statistic = t = -7.63
Degrees of freedom = n - 1 = 50 - 1 = 49
P-value = 0.0000 ...Using excel formula, =TDIST (7.63, 49, 1)
Decision: P-value< 0.05, reject H_0.
Conclusion: There is sufficient evidence to support the claim that the true mean age of millionaires in the US is less than 62 years old.

The top five megacities are all located in Asia. Asia is the continent with the most overall megacities with 19 (or 20 if you count Turkey as part of Asia). Europe has five megacities (including Istanbul, Turkey). Africa, North America, and South America each have three megacities.
In the Customer Service Department, 9 out of every 10 incoming calls are usually answered after the first ring, if they have 95% of their staff working the phones. On one particular day, the Customer Service Department had 100% of their staff working the phones. Did they answer at least 9 out every 10 incoming calls after the first ring?
When 95% of the staff is working, 9 out of 10 calls are answered after the first ring, when 100% of the staff is working, this should still be the case so the answer is probably yes.
What happens when 100% of the staff is working?When fewer staff are working, the response rate of the company should be less so more staff should equal a higher response rate.
This means that if 100% of the staff is working as opposed to 95%, 9 out of 10 calls will most probably be picked up after the first ring.
