Answer:The importance of sample size calculation cannot be overemphasized. A research can be conducted for various objectives. A smaller sample will give a result which may not be sufficiently powered to detect a difference between the groups and the study may turn out to be falsely negative leading to a type II error.
Answer:
It is not necessarily important to avoid smaller sample sizes but if is way more beneficial if you collect a larger sample size.
Step-by-step explanation:
Later sample sizes help you to get a more accurate result. While smaller sample sizes are less reliable. Hope I helped sorry if not! Have a wonderful day!

Answer:
x = 3
Step-by-step explanation:
15x + 2 = 9x + 20
Now solve for x
Subtract 2 from each side
15x = 9x + 18
Subtract 9x from each side
6x = 18
Divide each side by 6
x = 3
Answer: x=3
Step-by-step explanation:
When you have two parallel lines cut by a transversal (line that goes across them), it forms special angles. One of those special angles is alternate interior angles. Alternate meaning opposite sides of the transversal and interior meaning on the inside of the parallel lines. The special relationship of these angles is that they are equal.
9x+20 and 15x+2 are alternate interior angles which means they are equal. Set them equal to each other to solve for x.
9x+20= 15x+2. Subtract 9x from both sides.
20= 6x+2. Subtract 2 from both sides.
18=6x. Divide both sides by 6.
3=x

The formula for the area of a semicircle is
π (pi) * r^2 /2The Diameter of your semicircle is 2, and the radius is half of the diameter, so the radius (r) of the semicircle is 1.
3.14 * 1^2 /2Solve 1^2
3.14 * 1 / 2According to PEMDAS, you solve the Multiplication first.
3.14 * 1 = 3.14Now divide with your dividend above.
3.14 / 2 = 1.57Therefore, your answer is 1.57

round the number 6,438,593 to the nearest 1,000
6,438,593
The answer would be: 6,439,000
5 or higher gets the next number to round up meaning that because of the 5 in 593 would make the 8 in the thousands place round up to 9.

so would it be one solution, no solution or infinite solution?
Answer:
No solution would mean that there is no answer to the equation. It is impossible for the equation to be true no matter what value we assign to the variable. Infinite solutions would mean that any value for the variable would make the equation true. ... Note that we have variables on both sides of the equation.

A right rectangular pyramid is sliced by a plane that is perpendicular to the base of the pyramid.
Which of the following shapes could result from the slicing?
triangle
O rectangle
O square
O pentagon
A triangle is obtained when a right rectangular pyramid is sliced by a plane that is perpendicular to the base of the pyramid.
A rectangular pyramid is a three-dimensional object with a rectangle base and a triangular face corresponding to each of the sides of the base.
Cross - sections perpendicular to the base and through the vertex will be triangles. A triangle is obtained as a right rectangular pyramid is sliced by a plane that is perpendicular to the base of the pyramid.

e) What does the value of the mean absolute deviation tell you about the spread of the data? (2 points)
Answer:
What the absolute deviation tells me about the spread of data is, that there is a deeper mean to the mean. First you have to find the actual mean. Next, you find the mean for the lower and upper quartiles. After that, you have to find the absolute deviation for the lower and upper quartiles.

(Also this answer is for Part E)
Answer: A) The histogram is skewed left meaning that the median will be more than the mean of the data. As the study goes onward in terms of age, more and more children are studied to play at least an hour a week of video games. Barley any children below the age of 5 play video games for at least an hour a week, but once they hit the age of 6, more and more kids are playing video games. Kids aged fifteen to seventeen have the most amount of kids that do play at least an hour of video games per week. In a graph, this may show a J-shaped curve that starts low, then has a large increase to eventually level off and begin gradually getting larger as the ages increase.B) The following statement, “Children are typically introduced to video games between the ages of six to eight” is a true statement. The graph shows that a very small percentage of children from birth to five years old play video games, but suddenly, once they have turned 6, there is practically a 60% increase in how many kids are playing video games one hour a week. It is from the age 6 that the kids start off and are introduced to the video games, as more and more kids end up playing as well as the grow older.c) Knowing that five hundred families that lived in varied cities were randomly surveyed for this data, then it is possible to make a valid conclusion. To make accurate and valid conclusions, the data should be a good representation of the overall population, one that is large and random. The data collected was not all from one specific area, and instead was from a large sample size from different cities are regions all over. This was also done randomly, and did not only focus on people more or less likely to play video games. This means that it is possible to make valid conclusions.

A shop in the mall is 7 metres by 12 metres. How much would it cost to recarpet the shop with the carpet that costs £4 per square metre
Answer:
£336

People of the past and present judge each other by their class. This could relate to how much wealth they have as well as their social class or economic status. These judgments separate us as a society, and we live our lives around these judgments. Class, in simple words, is a group of people or things categorized by the quality and economic status. This relates to the novel The Great Gatsby by some of the characters in the novel, such as Tom and Daisy Buchanan who are sardonic and in love with material luxury.
·
Daisy Buchanan is a beautiful, charming woman from Louisville, Kentucky. For a while, she was with Gatsby before he went to war but later married Tom Buchanan because he had a promised wealthy life that he could provide her. In the novel, during the reunion at Daisy's house in the east egg, "'You make me feel uncivilized, Daisy,' I confessed on my second glass of corky but rather impressive claret. 'Can't you talk about crops or something?'" Nick's statement shows the wealthy class of the east egg and how Daisy flaunts her wealth to everybody instead of enjoying the people around her.
