You read that a study is planned for which a test of hypothesis will be done at significance level α = 0.10. Statisticians have calculated that for a certain effect size, the power is 0.7. What are the probabilities of Type I and Type II errors for this test?
Answers
Answer:
The probabilities of Type I is 0.10.
The probability of type II error is 0.3
Step-by-step explanation:
Consider the provided information.
Type I error: If we reject the null hypothesis when null hypothesis is true then it is called type I error.
The type I error is denoted by α.
Type II error: If we fail to reject the null hypothesis when null hypothesis is false then it is called type II error.
The type II error is denoted by β.
It is given that significance level α = 0.10.
Thus, the probabilities of Type I is 0.10.
The power of the test is:
It is given that power is 0.7.
Therefore,
Hence, the probability of type II error is 0.3

What is an expression?
An expression in mathematics is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division, etc.)
A phrase in language may contain an action on its own, but it does not constitute a whole sentence.

Final answer:
The simplified form of the expression \sqrt[3]{686x {}^{4}} * y {}^{7} is 2y^7x * \sqrt[3]{x}. This is achieved by breaking down 686 into its prime factors and simplifying under the cube root.
Explanation:
To simplify the given expression \sqrt[3]{686x {}^{4} } y {}^{7}, we first break down 686 into its prime factors. 686 = 2 * 7 * 7 * 7 or 2 * 7^3. Now we can simplify the given expression by solving it inside the cube root first: \sqrt[3]{2 * 7^3 * x^4}, which simplifies to 2y^7x * \sqrt[3]{x}
\sqrt[3]{686x {}^{4}} * y {}^{7} = 2y^7x * \sqrt[3]{x}

The area of a triangular painting is 50 in.² the base is 20 inches what is the height
Answers
The height of the triangle is 5 inches.
Area of the triangle:
The region occupied by a triangle within its sides is known as the area of the triangle. The area of a triangle can be calculated by the calculating product of the base and height of the triangle with a half i.e 1/2. The formula for the area of the triangle is given by
Area of triangle = (1/2) × base × height
Here we have
Area of the triangle = 50 in²
The base of the triangle, b = 20 inches
As we know,
Area of the triangle = 1/2 (base × height)
From the given data,
=> 50 = 1/2 (20 × height)
Multiply by 2 on both sides
=> 100 = (20 × height)
Divided by 20 into both sides
=> 100/20 = (20 × height)/20
=> 5 = height
=> height = 5 in
Therefore,
The height of the triangle is 5 inches.

Answer:
The number of times organism B's population is larger than organism A's population after 8 days is 32 times
Step-by-step explanation:
The population of organism A doubles every day, geometrically as follows
a, a·r, a·r²
Where;
r = 2
The population after 5 days, is therefore;
Pₐ₅ = = 32·a
The virus cuts the population in half for three days as follows;
The first of ta·2⁵ he three days = 32/2 = 16·a
The second of the three days = 16/2 = 8·a
After the third day, Pₐ = 8/2 = 8·a
The population growth of organism B is the same as the initial growth of organism A, therefore, the population, P₈ of organism B after 8 days is given as follows;
P₈ = a·2⁸ = 256·a
Therefore, the number of times organism B's population is larger than organism A's population after 8 days is P₈/Pₐ = 256·a/8·a = 32 times
Which gives, the number of times organism B's population is larger than organism A's population after 8 days is 32 times.
Final answer:
Organism A's population at the end of 5 days is 2^5. After 5 days, a virus cuts it in half for 3 days. Organism B's population at the end of 8 days is 2^8. To find the difference, subtract organism A's population from organism B's population.
Explanation:
Organism A's population doubles every day for 5 days, so the population at the end of 5 days is 25. After 5 days, a virus cuts the population in half for 3 days, so we need to find (25) * (2-1)3. Using the rule of exponents, we can rewrite this expression as (25+(-1*3)), which simplifies to 2-4.
Organism B's population grows at the same rate but is not infected with the virus. After 8 days, the population is 28.
To find out how much larger organism B's population is than organism A's population, we need to subtract the population of organism A from organism B. So, 28 - 2-4 is the answer.

Option D
Step-by-step explanation:
We already have two reasons to support two sides. We have the reflexive property and that the base is divided by a midpoint. So we will need an angle.
Also, AC is the median so it divides into two congruent angles and parts
Option D, because the reflexive property is then included in that part
