Identify the type I error and the type II error that corresponds to the given hypothesis. The proportion of people who write wit

aalyn [17]

Answer:

Step-by-step explanation:

The type I error occurs when the researchers rejects the null hypothesis when it is actually true.

The type II error occurs when the researchers fails to reject the null hypothesis when it is not true.

Null hypothesis: The proportion of people who write with their left hand is equal to 0.23: p =0.23

Type I error would be: Fail to reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually different from 0.29

Since 0.29 is assumed to be the alternative claim.

Type II error would be: Reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually 0.29

Still with the assumption that 0.29 is the alternative claim.

I don't know how to solve it?

Grace [21]

Just turn 5/6ths into x/32nds. For example I could turn 1/2 into 2/4. And 2/4 into 4/8.

kumpel [21]

Answer:

6.16?

Step-by-step explanation:

Not completely sure but if you divide 256 by 40 you get six remainder 16 not sure if I did it right so sorry if I am wrong

At the indicated point find (a) the slope of the curve and (b) an equation of the tangent line.

Marianna [84]

Answer:

Slope of the Curve: $f'(x)=\frac{-6}{x^2}$

Equation of Tangent Line: y + 3 = -3/2(x + 2)

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate
y₁ - y coordinate
m - slope

Calculus

The definition of a derivative is the slope of the tangent line.

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Quotient Rule: $\frac{d}{dx} [\frac{f(x)}{g(x)} ]=\frac{g(x)f'(x)-g'(x)f(x)}{g^2(x)}$

Step-by-step explanation:

Step 1: Define

$f(x)=\frac{6}{x}$

Step 2: Take Derivative

Quotient Rule: $f'(x)=\frac{0(x)-6(1)}{x^2}$
Multiply: $f'(x)=\frac{0-6}{x^2}$
Subtract: $f'(x)=\frac{-6}{x^2}$

Step 3: Find Instantaneous Derivative

Substitute in x: $f'(x)=\frac{-6}{(-2)^2}$
Exponents: $f'(x)=\frac{-6}{4}$
Simplify: $f'(x)=\frac{-3}{2}$

This value shows the slope of the tangent line at the exact value of x = 2.

Substitute: y + 3 = -3/2(x + 2)
