A researcher reports that the standard deviation in population is A is q= 2.3 and the standard deviation in population B is q=4.3. Which population is associated with the highest power to detect an effect?
Answers
Answer:
Population A
Step-by-step explanation:
Usually in statistics, the more we increase the sample size, the more the standard deviation decreases. Similarly, the more we decrease the sample size, the more the standard deviation increases.
Finally, the more the standard deviation or error of Variance the lesser the power to detect an effect.
In this question, Population B has a greater standard deviation and thus would not have as much power as Population A in detecting an effect.
Thus Population A with standard deviation of 2.3 will have highest power to detect an effect.

There are two squares.ONe has a side length of 12 inches and the other has a side length of 14 inches.What is he total area of both squares?
Answers
Answer:
340 in^2
Step-by-step explanation:
1. First square
A = l*w = 12^2 OR 12*12 = 144
2. Second square
A = l*w = 14^2 OR 14*14 = 196
3. Combined Area
144+196=340
The area of a square is found by squaring the side length, which is the same as multiplying two of the sides together.
Square 1: 12 x 12 = 144 square inches.
Square 2: 14 x 14 = 196 square inches.
Total area = 144 + 196 = 340 square inches.

C) Peta, because she invests the most
Step-by-step explanation:
The additional $70 that Peta invests is equivalent to more than 2 years' interest at either of the other rates. Not only does Peta invest more money, she does so at a higher interest rate.
Peta will have the most money in her account when she closes it.

a) The average rainfall of the last week was 35 mm. If the records of daily
rainfall from Sunday to Friday were 45 mm, 22 mm, 28 mm, 36 mm, 30 mm
and 24 mm, find the rainfall on Saturday.
Answers
Answer:
The rainfall on Saturday was of 60 mm.
Step-by-step explanation:
Average rainfall:
The average rainfall is given by the total rainfall divided by the number of days(7). So
If the records of daily rainfall from Sunday to Friday were 45 mm, 22 mm, 28 mm, 36 mm, 30 mm and 24 mm
On Saturday it was of x mm. So
[tex]35 = \frac{45 + 22 + 28 + 36 + 30 + 24 + x}{7}[/tex]
[tex]185 + x = 245[/tex]
[tex]x = 245 - 185[/tex]
[tex]x = 60[/tex]
The rainfall on Saturday was of 60 mm.

Answers
Answer:
m<B = 93°
Step-by-step explanation:
Based on the inscribed quadrilateral theorem, the opposite angles of a cyclic quadrilateral are supplementary.
Thus:
m<B + m<D = 180°
Substitute
m<B + 87° = 180°
m<B = 180° - 87°
m<B = 93°

Which triangle can be used to find the slope of the line shown? explain your answer
Answers
Answer:
A right triangle contains a right angle, so it must have two sides that are perpendicular. If the slopes of two sides can be shown to be negative reciprocals of each other, then it can be concluded that a right angle is formed. If a triangle contains a right angle, then it is a right triangle
Step-by-step explanation:
to determine if a triangle is a right triangle using slopes, you have to understand perpendicular slopes/negative reciprocals.
You can calculate the slope of all 3 sides of the triangle and if two of the slopes are negative reciprocals, then those two lines intersect creating a right angle/right triangle.
Let's say there's triangle ABC.
If the slope of AB is 1/2
and the slope of BC is 2/5
and the slope of CA is -2/1
then AB and CA intersect resulting in a right angle (triangle).

what's the answer! Consider having a personal loan that spans 5 years. The loan was only taken out for $6000, but the interest rate was a higher fixed percentage of 5.99%. How much interest will you have paid after it is paid off?
Answers
Answer: $179.70
Step-by-step explanation:
The simple interest will be:
= (Principal × Rate × Time) / 100
= ($6000 × 5.99% × 5) / 10
= ($6000 × 0.0599 × 5) / 10
= $1797 / 10
= $179.70
Therefore, the total interest on the loan is $179.70
