Three of the following numbers add up to the number 31: 17, 3, 2, 19, 5.
If numbers add up, they reach the predicted total; they make sense. If the numbers don't add up, the overall sum doesn't make sense in light of the individual sums.
How to calculated numbers add up ?Only 17 + 19 - 5 = 31 can be used to "add" three of the given numbers to the number 31.
Only these sums can be created from 3 of the numbers if only positive signs are permitted.
{10, 22, 24, 24, 25, 26, 27, 38, 39, 41}
Any of these sums can be earned if either positive or negative signs are permitted.

Suppose it is know that sigma is equal to 30. What is the minimum number of people the pollster should survey in order to have a margin of error of 10 miniutes at 95% confidence? show work.
To determine the minimum number of people the pollster should survey in order to have a margin of error of 10 minutes at 95% confidence, we can use the following formula:
n = (Z^2 * p * (1 - p)) / (E^2)
where:
n = the minimum number of people the pollster should survey
Z = the z-score corresponding to the desired level of confidence (for a 95% confidence level, the z-score is approximately 1.96)
p = the estimated proportion of the population that holds a particular opinion or characteristic (in this case, we will assume that p = 0.5, since we are given that sigma is equal to 30 and we want to find the minimum number of people needed to achieve a margin of error of 10 minutes)
E = the desired margin of error (in this case, E = 10 minutes)
Substituting these values into the formula, we get:
n = (1.96^2 * 0.5 * (1 - 0.5)) / (10^2)
Simplifying this expression, we get:
n = (3.8416 * 0.25) / 100
= 0.09604 / 100
= 0.0009604
Since n must be a whole number, we need to round up to the nearest whole number. In this case, the minimum number of people the pollster should survey is 1.
Therefore, the minimum number of people the pollster should survey in order to have a margin of error of 10 minutes at 95% confidence is 1.
A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 439 439 gram setting. It is believed that the machine is underfilling or overfilling the bags. A 26 26 bag sample had a mean of 443 443 grams with a variance of 225 225 . Assume the population is normally distributed. Is there sufficient evidence at the 0.01 0.01 level that the bags are underfilled or overfilled?
A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 447.0 gram setting.
Find the solution ?So, Null hypothesis :447
It is believed that the machine is under filling the bags
So, Alternate hypothesis :
n = 41
Population standard deviation =
x = 443
We will use z test since n > 30 and we are given the population standard deviation.
Use z table to find p value
z = 443 - 447/ 21/ √41
z = - 1.2196
p value = 0.1131
α = 0.02
p value > α
So, we fail to reject null hypothesis.
So, its bag filling machine works correctly at the 447.0 gram setting.

Your project will be completely defined from beginning to end by a problem statement or opportunity statement. Issue Statement: You want to update or improve an existing procedure or service.
What opportunity or Problem project addressing?Opportunity in relation to a project mostly refers to the value expected from the project output. Initial cost and outcome projections lead to a value expectation that is greater than the project's cost. This disparity may suggest a modestly reasonable prospect or one that is outrageously idealistic.
Therefore, Opportunity Statements are useful when developing new procedures or services.

Answer:god
Explanation:
Suppose that E and F are two events and that P(E)= 0.7 and P(FIE) = 0.3. What is P(E and F)? P(E and F) = (Simplify your answer.)
The calculated value of P(F|E) is 0.4.
Then the conditional probability that the event will occur given that has already occurred is given by the following formula:
P(B|A) = (P(A∩B)) / P(A)
Here the two events given are E and F .
P(E and F) or P(E∪F) = 0.3
and P(E)= 0.7
As per the above formula that we have already discussed, the formula can be written as:
P(F|E) = P(E ∩ F) / P(E)
P(F|E) =0.3/0.7
P(F|E) = 3/7
P(F|E) = 0.4
What in likelihood are E and F?The capital letters E and F in the discussion that follows stand in for potential experiment results, and P(E) denotes the likelihood that outcome E will be seen. The results of E or F can be listed as the results of E followed by the results of F for events that don't happen simultaneously.
How can you demonstrate the independence of two events?If knowing whether A happened has no effect on the likelihood that B will also occur, then events A and B are independent. Mathematically, the following statements are equivalent: P(A and B) = P(B A) = P(B) P(B|A) = P(B) (A).

What section of the outline is represented by "A Continents of the World?"
Answer:
The section of the outline represented by "A Continents of the World" is likely "The World." This section would likely include information about the different continents that make up the world, such as Africa.
In an outline, letters or numbers are often used to indicate the hierarchical structure of the information, with "A" representing a sub-section of the main section, which in this case is "The World."
Therefore, "A Continents of the World" would likely be a sub-section of "The World" in the outline.

What is the basis for the demand or need for the goods/service to be produced the project
Answer:
Explanation:
The demand or need for a particular good or service is based on the wants and needs of consumers. When people have a need or want for a particular product or service, they will be willing to pay for it, which creates demand. This demand can be driven by a variety of factors, such as changes in consumer preferences, population growth, economic conditions, and technological advances.
In order for a project to be successful, it is important to understand the basis for the demand for the goods or services being produced. This may involve conducting market research to determine the needs and preferences of consumers, as well as analyzing trends in the industry and the competitive landscape. Understanding the demand for the goods or services being produced can help inform the development of the project and help ensure that it meets the needs of consumers.
