a type i error means that the hypothesis test has failed to detect a real treatment effect. true or false
Answers
A type I error means that the hypothesis test has failed to detect a real treatment effect. This statement is incorrect. A type I error is also known as a false positive error, and it occurs when the null hypothesis is rejected even when it is true.
A type I error occurs when a hypothesis test rejects a null hypothesis when it is actually true. It's also referred to as a "false positive" because the test indicated that there is a difference when there isn't one.
The level of significance (also known as alpha) is frequently utilized to calculate the likelihood of making a type I error. It's usually set at 0.05 or 0.01, which means there's a 5% or 1% chance of making a type I error if the null hypothesis is true.

8 The table shows number of bottles of water four
students drank. One bottle holds 335 milliliters. How
many more fluid ounces did Michael drink than
Lydia? (Hint: 1 fl oz ≈ 30 mL)
Kyle = 5 Bottles of Water
Lisa = 4 Bottles of Water
Lydia = 3 Bottles of Water
Michael = 6 Bottles of Water
Answers
Michael drinks 33.5 fl oz more fluid ounces than Lydia.
Given in question,
30 ml = 1 fl oz
1 ml = 1/30 fl oz
1 bottle = 335 milliliters
No. of bottles of water Michael drank = 6
= 6 * 335 milliliters
= 2010 milliliters
= 2010/30 fl oz
= 67 fl oz
No. of bottles of water Lydia drank = 3
= 3 * 335 milliliters
= 1005 milliliters
= 1005/30 fl oz
= 33.5 fl oz
Therefore, 67 - 33.5 = 33.5
Hence, Michael drinks 33.5 fl oz more fluid ounces than Lydia.

a.)16 lb
b.)160lb
c.)625lb
d.)1600lb
e.)120000lb
Answers
The number of pounds of cotton candy are consumed by a 12 year old is 120,000Ib
Finding the product of two or more numbers in mathematics is done by multiplying the numbers. It is one of the fundamental operations in mathematics that we perform on a daily basis. Multiplication tables are the main use that is obvious.
In mathematics, the repeated addition of one number in relation to another is represented by the multiplication of two numbers. These figures can be fractions, integers, whole numbers, natural numbers, etc. When m is multiplied by n, either m is added to itself 'n' times or the other way around.
Multiplication Formula
The multiplication formula is given by:
Multiplier × Multiplicand = Product
From the given information, 10,000 pounds of cotton candy are consumed each year.
Then, the number of pounds of cotton candy are consumed by a 12 year old is 10,000*12=120,000.
Thus, the correct option is e 120000 Ib

costs her $200, and each wreath costs her $10 for
material. If she sells each wreath for $30, how many
wreaths does she have to sell to break even?

Record your answer and fill in the bubbles on

place value
Answers
Answer: 10 wreaths
Step-by-step explanation:
First identify the terms.
She has a booth that cost $200. This price will not change thus making it a Fixed cost.
Making a wreath would cost her $10 each time so this is a Variable cost.
She sells the wreath for $30 so this is the selling price.
Breakeven = Fixed Cost / Contribution margin
Contribution margin = Selling price - Variable cost
= 30 - 10
= $20
Breakeven point = 200/20
= 10 wreaths
Let U = {(x, y, z) € R^3 | x + 2y – 3z =0}. a) (2pt) Show directly (by verifying the conditions for a subspace) that U is a subspace of R^3. You may not invoke results learned in class or from the notes. b) (2pts) Find a basis for U. You must explain your method. c) (1pt) Using your answer from part b) determine Dim(U).
Answers
a) U is subspace of R^3.
b) The set {(3, -2, 0), (0, 1/2, 1)} is a basis for U.
c) 2.
a) To show that U is a subspace of R^3, we need to verify the following three conditions:
i) The zero vector (0, 0, 0) is in U.
ii) U is closed under addition.
iii) U is closed under scalar multiplication.
i) The zero vector is in U since 0 + 2(0) - 3(0) = 0.
ii) Let (x1, y1, z1) and (x2, y2, z2) be two vectors in U. Then we have:
x1 + 2y1 - 3z1 = 0 (by definition of U)
x2 + 2y2 - 3z2 = 0 (by definition of U)
Adding these two equations, we get:
(x1 + x2) + 2(y1 + y2) - 3(z1 + z2) = 0
which shows that the sum (x1 + x2, y1 + y2, z1 + z2) is also in U. Therefore, U is closed under addition.
iii) Let (x, y, z) be a vector in U, and let c be a scalar. Then we have:
x + 2y - 3z = 0 (by definition of U)
Multiplying both sides of this equation by c, we get:
cx + 2cy - 3cz = 0
which shows that the vector (cx, cy, cz) is also in U. Therefore, U is closed under scalar multiplication.
Since U satisfies all three conditions, it is a subspace of R^3.
b) To find a basis for U, we can start by setting z = t (where t is an arbitrary parameter), and then solving for x and y in terms of t. From the equation x + 2y - 3z = 0, we have:
x = 3z - 2y
y = (x - 3z)/2
Substituting z = t into these equations, we get:
x = 3t - 2y
y = (x - 3t)/2
Now, we can express any vector in U as a linear combination of two vectors of the form (3, -2, 0) and (0, 1/2, 1), since:
(x, y, z) = x(3, -2, 0) + y(0, 1/2, 1) = (3x, -2x + (1/2)y, y + z)
Therefore, the set {(3, -2, 0), (0, 1/2, 1)} is a basis for U.
c) Since the basis for U has two elements, the dimension of U is 2.

Consider that the area of a sector of a circle is given by:
\(A=\frac{\theta}{360}\pi r^2\)where θ is the angle of the sector and r is the radius.
For θ=40 and r = 8cm, you obtain:
\(A=\frac{40}{360}\pi(8cm)^2=22.34cm^2\)The area of the small sector is about 22.34 cm^2.

The interpretation is that 8% of the variation in the dependent variable can be explained by the variation in the independent variable. (B)
The coefficient of determination, r^2, is a measure of how much of the variation in the dependent variable can be explained by the variation in the independent variable.
It is calculated by squaring the correlation coefficient, r, between the two variables. In this case, r^2 is equal to 0.08, which means that 8% of the variation in the dependent variable can be explained by the variation in the independent variable.
This means that the independent variable has a relatively small effect on the dependent variable, and there are likely other factors that contribute to the variation in the dependent variable.
