Answers
Answer: greater than 0.3
Step-by-step explanation:
On edge
The margin of error for a 95% confidence level will be greater than 0.3.
What is a confidence interval?A random population parameter is likely to be included in a confidence interval, which is a range of values that is limited by the statistic's mean. The confidence level is the percentage of probability, or certainty, that, after repeated random sample draws, the confidence interval would include the true population parameter.
Given:
A confidence level is 95%.
The formula to calculate the margin of error:
The margin of error = Z x S/√n.
Where S is the standard deviation and n is the sample size.
The corresponding z-score of the confidence level is 95%.
So, the margin of error will be always greater than 0.3.
Therefore, the margin of error will be always greater than 0.3.

AUTHORITY ? description In your own words .this phrase has probably done more damage to investors than just about any other in all of market history.
Answers
Answer:
Authority is the accepted power of a person or an organization to lead another person or group. In a political sense, authority also stands for the power and dominion over an area or country held by the government. Authority legitimized by law or government is called 'competent authority'. A person who is generally respected by knowledge or status in a certain area is 'authoritative' in that area.
Authority regulates the relationships between people in society. If authority is absent, anarchy reigns. The difference between authority and power is that authority is legitimate. It has the right to exercise this power by, for example, imposing sanctions.

You just completed your math course and you want to calculate your overall grade. You know that tests are weighted 15%, quizzes 10%. projects 35%, participation 35%, and the final exam 5%. What is your overall grade if you scored the following in each category?
Answers
Your overall grade, rounded to the nearest hundredth, is approximately 86.35%.
To calculate your overall grade, we need to assign weights to each category and then calculate the weighted average based on your scores.
Let's assume your scores in each category are as follows:
Tests: 85%
Quizzes: 90%
Projects: 92%
Participation: 80%
Final Exam: 88%
Now, let's calculate the weighted average:
Tests: 15% weight × 85% score = 12.75
Quizzes: 10% weight × 90% score = 9.00
Projects: 35% weight × 92% score = 32.20
Participation: 35% weight × 80% score = 28.00
Final Exam: 5% weight × 88% score = 4.40
Overall Grade = Sum of weighted scores / Total weight
Overall Grade = (12.75 + 9.00 + 32.20 + 28.00 + 4.40) / 100
Overall Grade ≈ 86.35%
Therefore, your overall grade, rounded to the nearest hundredth, is approximately 86.35%.

Jillian picked coins from her piggy bank and recorded the number of coins in the table below.
Based on the results shown in the table, what is the probability that the coin Jillian picks will be a quarter
Answers
Answer:
1/8
Step-by-step explanation:
There are 24 coins total. 3 of them are quarters. So Jillian has a 3 in 24 chance of picking up a quarter. Simplifying 3/24 we get 1/8
The probability of randomly picking a quarter is P = 0.125
How to get the probability?
If we assume that all the coins have the same probability of being randomly picked, the probability of picking a particular type of coin is equal to the quotient between the number of coins of that type that we have, and the total number of coins.
In this case, we have 3 quarters, and a total of:
T = (6 + 7 + 8 + 3) = 24
Then the probability of randomly picking a quarter is:
P = 3/24 = 0.125

The ratio of red cars to blue cars in a parking lot was 5 : 3. If there were 40 red cars, how many blue cars were there?
Answers
Answer:
24 blue cars
Step-by-step explanation:
In this problem, one is given the ratio of red to blue cars in the parking lot. One is given the actual number of red cars, and one is asked to find the number of blue cars. One can set up a proportion; ratio to actual, then solve to find the number of actual blue cars using the method of cross-products. One can set up the proportion using the ratios, but it is easier to express the proportion as the equality of two fractions. Thus, the following equation can be formed, let the parameter (x) represent the actual amount of blue cars;
[tex]\frac{red}{blue}= \frac{5}{3} = \frac{40}{x}[/tex]
Cross products,

Peggy constructed the 95 percent confidence interval (4.8,5.2) to estimate the slope of a regression model for a set of bivariate data with 24 data values. Peggy claims that the width of the confidence interval will increase if a sample size of 30 is used, all other things remaining the same. Quincy claims that the width of the confidence interval will decrease if a sample size of 30 is used. Which statement is true about the claims made by Peggy and Quincy?
Answers
Answer:
Quincy's claim is correct.
Step-by-step explanation:
Margin of error of a confidence interval:
The margin of error of a confidence interval decreases is the sample size increases, that is, if the sample size increases, the width of the interval decreases.
In this question:
Sample size of increases to 30 from 24, which means that the width of the interval will decrease.
