Use technology to find the P-value for the hypothesis test described below. The claim is that for a smartphone carrier's data speeds at airports, the mean is μ=11.00 Mbps. The sample size is n=14 and the test statistic is t=1.484. P-value=nothing (Round to three decimal places as needed.)
Solution :
The null and alternative hypothesis is given by
[tex]$H_0: \mu = 11$[/tex]
[tex]$H_a: \mu \ne 11$[/tex]
Assume that the level of significance, α = 0.05
The t-test statistics is, t = 1.484
Degree of freedom :
df = n - 1
= 14 - 1
= 13
The P-value is given by
P-value = 2P (T>|t|)
= 2P(T>|1.484|)
= 2P(T>1.484)
= 2(=T.DIST.RT(1.484,13))
= 0.05
Can someone show me the steps to solve this I will give u a Brainly crown (10points)

Answer:
Step-by-step explanation:
1/4a + 1/3a + 8 = 22
Collect like terms
1/4a + 1/3a = 22 - 8
Simplify
3a+4a/12 = 14
7/12a = 14
Divide both sides by 7/12
a = 14 ÷ 7/12
= 14 × 12/7
= 168/7
= 24
a = 24
Check:
1/4a + 1/3a + 8 = 22
1/4(24) + 1/3(24) + 8 = 22
24/4 + 24/3 + 8 = 22
6 + 8 + 8 = 22
22 = 22
Write a rational equation that relates the desired percentage to the amount of % acid solution that needs to be added to liter of % acid solution to make a blend that is % acid, where < < . What is a reasonable restriction on the set of possible values of ? Explain your answer.
This question is incomplete
Complete Question
Write a rational equation that relates the desired percentage p, to the amount A of a 30% solution that needs to be added to 1 liter of 10% acid solution to make a blend that is p% acid, where 0<p<100 . What is a reasonable restriction on the set of possible values of ? Explain your answer.
Answer:
100(0.1 + 0.3A)= (1 + A) P
Step-by-step explanation:
A of a 30% solution that needs to be added to 1 liter of 10% acid solution to make a blend that is p% acid,
Hence,
10% of 1 + 30% of A = p%(1 + A)
0.10 + 0.3A = (p/100)(1 + A)
Divide both sides by 1 + A
0.1 + 0.3A/ 1 + A = p/100
Cross Multiply
100(0.1 + 0.3A) = 1 + A(p)
From the above calculation, we can see that, the blend that would be formed is not lower than 10% or greater than 30%
10% < p< 30%

Using the graph. which of the following ordered pairs represents solutions to this inequalities? Select all that apply
(0,10)
(5,12)
(8,6)
(10,4)
(12,5)
(15,2)
Answer:
(8,6) and (10,4)
Step-by-step explanation:
solutions to the system of inequalities are in the purple shaded area, coordinates not landing in the purple shaded area are incorrect. The purple shaded area represents solutions for both lines red and blue.
Incorrect answers:
(0,10) because it lands in the blue shaded area ( meaning its the solution for only line blue and not line red)
(5,12) because it lands in the red shaded area ( meaning its the solution for only line red and not line blue)
(12,5) in red only
(15,2) in red only

Is 5x + 2 a numerical expression?
Answer:
Yes
Step-by-step explanation:
Yes, this is a numerical expression because x represents a number. This number is unknown, so x = 1 --- 5x (1) + 2 is equivalent to 5x + 2. 5x (1) +2 is a numerical expression, SO that means that 5x + 2 is a numerical expression.

. Distance from A to B is 2 inches in the drawing. If the scale is 1 in: 200
miles, find the actual distance from A To B
Answer:
400 miles
Step-by-step explanation:
If 1 inch is equal to 200 miles and the distance from A to B is 2 inches, multiply 200 × 2 to get 400
Answer:
The actual difference is 400 inches.
Step-by-step explanation:
To find the actual distance, you multiply the distance (which is 2 inches), To the scale 1:200. 2 x 200 = 400. Therefore the actual distance which is 400 inches.

Answer:
x = 25
Step-by-step explanation:
A segment joining the midpoints of 2 sides of a triangle is half the length of the third side, that is
x - 8 = [tex]\frac{1}{2}[/tex] × 34 = 17 ( add 8 to both sides )
x = 25

Select the statement that describes this expression: 13 + fraction 1 over 2 x (6 ÷ 2 + 6) A: 13 more than half of 6 more than the quotient 6 and 2 B: 13 more than half of the quotient of 6 and 6 minus 2 C:Half of 13 multiplied by the quotient of 6 and 2 plus 3 D:13 plus half of 6 divided by 2, then subtract 6
Answer:
"13 plus half of 6 divided by 2, then add 6"
Step-by-step explanation:
We need to select the statement that describes this expression :
[tex]13+\dfrac{1}{2}\times (\dfrac{6}{2}+6)[/tex]
Here 13 is added to half of 6 divided by 2 and then add 6.
Hence, this is the correct answer "13 plus half of 6 divided by 2, then add 6).

Consider the graph of the polynomial function. Which of the following shows three binomial factors of the function?
Question 16 options:
A)
(x – 1)(x – 2)(x – 3)
B)
(x + 1)(x + 3)(x – 2)
C)
(x + 2)(x – 1)(x – 3)
D)
(x + 1)(x + 2)(x + 3)
Answer:
C
Step-by-step explanation:
the three binomial factors are (x+2)(x-1)(x-3)
Answer:
C
Step-by-step explanation:
Given a zero x = a then the corresponding factor is (x - a )
Here the zeros ( where the graph crosses the x- axis ) are at
x = - 2, x = 1 and x = 3
Thus the corresponding binomial factors are
(x - (- 2) ), (x - 1) and (x - 3), that is
(x + 2), (x - 1), (x - 3) → C
