Is the 8 with the problem?
Answer:
We reject H₀
we accept Hₐ seeds in the packet would germinate smaller than 93%
Step-by-step explanation:
Test of proportions
One tail-test (left side)
93 % = 0.93
p₀ = 0,93
1.- Hypothesis
<h3>
H₀ ⇒ null hypothesis p₀ = 0.93</h3><h3>
Hₐ ⇒ Alternative hypothesis p = 0.875</h3><h3>
2.-Confidence interval 95 %</h3><h3>
α = 0,05 </h3><h3>
and </h3><h3>
z(c) = - 1.64</h3><h3>
3.- Compute z(s)</h3><h3>
z(s) = (p - p₀)/√(p₀*q₀)/n z(s) = (0.875-0.93)/√0.93*0.07)200</h3><h3>
z(s) = - 0,055/ √0.0003255</h3><h3>
z(s) = - 0.055/ 0.018</h3><h3>
z(s) = - 3,06</h3><h3>
4.-Compere z(c) and z(s)</h3><h3>
z(s) < z(c) -3.06 < -1.64</h3><h3>
z(s) is in rejection region, we reject H₀</h3>
Answer:
Step-by-step explanation:
Slope (m) =
ΔY
ΔX
= 0
θ =
arctan( ΔY )
ΔX
= 0°
ΔX = 6 – 2 = 4
ΔY = -3 – -3 = 0
Distance (d) = √ΔX2 + ΔY2 = √16 = 4
Equation of the line:
y = 0x – 3
When x=0, y = -3
The second statement is:
B: a + b = b + a
Which is the commutative property, so we know that this statement is true.
<h3>
Which statement is always true?</h3>
Remember that for integer numbers, we have the following properties:
- Commutative property: A + B = B + A
- Associative property: (A + B) + C = A + (B + C)
Now, in this case we know that a and b are integer numbers, first we can see that the second statement is:
B: a + b = b + a
Which is the commutative property, so we know that this statement is true.
The other 3 statements are false. You can see it by evaluating a = 0 and b = 1.
