A trapezoidal Riemann sum can be found by multiplying the width (the change in x) of each sub interval by the average of the y values of the two points at either end of the section and then adding up all of the sun intervals. Therefore, the trapezoidal approximation would equal 0.5(40) + 1.5(50) + 1(35) to get the answer of 130.

Alice works at a health care facility.
She has measured the hemoglobin levels of 200 people.
The data follows a normal distribution with a mean of 14 g/dL and a standard deviation of 1.
From the given data, we can conclude that the number of people has hemoglobin levels less than 13 will be
z = (13 - 14)/1
z = -1
Then the number of people will be
Number of people = 200 P(x < 13)
Number of people = 200 P(z < -1)
Number of people = 200 x 0.15866
Number of people = 31.732
Number of people ≅ 32
A number of people have hemoglobin levels greater than 14 will be
z = (14 - 14)/1
z = 0
Then the number of people will be
Number of people = 200 P(x > 14)
Number of people = 200 P(z > 0)
Number of people = 200 x 0.5
Number of people = 100

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

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.

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 social scientists, especially the economists, are moving deeply into ecology and the environment these days, with disquieting results. It goes somehow against the grain to learn that cost-benefit analyses can be done neatly on lakes, meadows, nesting gannets, and even whole oceans. It is hard enough to confront the environmental options ahead, and the hard choices, but even harder when the price tags are so visible. Even the new jargon is disturbing: it hurts the spirit, somehow, to read the word “environments,” when the plural means that there are so many alternatives there to be sorted through, as in a market, and voted on. Economists need cool heads and cold hearts for this sort of work, and they must write in icy, often skiddy, prose.
