Using the t-distribution, the test statistic is given as follows: t = -0.774.
What is the test statistic of a t-distribution test hypothesis?The test statistic is given by:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the tested value.s is the standard deviation of the sample.n is the sample size.The values of the parameters for this problem are:
[tex]\overline{x} = 0.1, \mu = 0.13, s = 0.26, n = 45[/tex]
Hence the test statistic is:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{0.1 - 0.13}{\frac{0.26}{\sqrt{45}}}[/tex]
t = -0.774.

what are the 2 reasons that the Louisiana purchase caused a debate in the usa
It was a debate between the northerners and southerners (forgive my spelling). The northerners feared the addition of more slave states and a corresponding lack of reprenestation of their intrests in the North. For the southern slave holders, new western lands would be a boon (helpful) to enslaved people and the Louisiana purchase threatened to entrench and expand their suffering to western territories.

Write the correct equation that passes through the points (0, 3) and (2, -5)
Answer:
y = -4x + 3
Step-by-step explanation:
(0, 3) and (2, -5)
m= (y2-y1)/(x2-x1)
m= (-5-3)/(2-0)
m= (-8)/2
m = -4
y - y1 = m(x - x1)
y - 3 = -4(x - 0)
y - 3 = -4x + 0
y = -4x + 3

FIND THE AREA OF THE (TRIANGLE!)
Answer:
114 cm^2
Step-by-step explanation:
area of a triangle= base x height divided by 2
Answer:
Triangle = 114 ft²
Rectangle = 374 ft²
Total figure = 488 ft²
Step-by-step explanation:
Triangle = 1/2 b*h
Triangle = 1/2(12x19)
Triangle = 1/2(228)
Triangle = 114 ft²
Rectangle = 22 x 17
Rectangle = 374 ft²
Total area = 114 ft² + 374 ft²
Total area = 488 ft²
10(p-7)=180 solve for p
Answer
The answer is p=25
Answer:
p = 25
Step-by-step explanation:
Isolate the variable, p. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
~
First, divide 10 from both sides of the equation:
(10(p - 7))/10 = (180)/10
p - 7 = 180/10
p - 7 = 18
Next, add 7 to both sides of the equation:
p - 7 (+7) = 18 (+7)
p = 18 + 7
p = 25
25 is your answer for p.

Three friends have done some job together and got paid and now they need to share
the money. The first friend gets $500 and of the rest of the money. After he took
his part, the second friend gets $800 and of the rest of the money. The third friend
gets $900. Which friend got the greatest amount?
Answer:
Third friend with $900
Step-by-step explanation:
All-in-all each individual got a specific amount of cash that is mentioned in the question. If we compare each of their amounts we can easily say that the third friend got the greatest amount which is $900. This is $400 more than the first friend and $100 more than the second friend. This would be different if the values were percentages instead of actual dollar values.

Please anyone help me on this
Answer:
Standard line equation:
y=ax+b
The point (5,1) is on the line. so :
1=a(5)+b → 1=5a+b
The point (1,-5) is also on the line. Then :
-5=a(1)+b → -5=a+b
Subtract the two equations in terms of a and b. we have:
6=4a → a=3/2 , b=-6.5
y=1.5x-6.5
