You conduct a simulation regarding students scores on a physics test. Your null hypothesis is
that the mean score on the test is less than or equal to 80 points. Your alternative hypothesis is
that the mean score is greater than 80 points.
You determine that the results of your simulation have a p-value of 0.06. What does this mean?
Under the tested hypothesis, the outcome of the simulation has a probability of 6%. With a significance level of 5%, you should FAIL to reject the null hypothesis.
The p-value is the probability of getting true null hypothesis.
What is Null Hypothesis and Alternative Hypothesis?Null hypothesis is a hypothesis of a test which assumes that there is no statistical relationship between two variables. This is the hypothesis which is being testes.
Alternative hypothesis assumes that there is a relationship between two variables.
Given that,
You conduct a simulation regarding students scores on a physics test.
Null hypothesis is that the mean score on the test is less than or equal to 80 points.
Alternative hypothesis is that the mean score is greater than 80 points.
p value = 0.06 = 6%
This means that there is only a 6% that the null hypothesis of yours is true.
So the p value tells you the probability of getting a true null hypothesis.
Hence the p value is the probability of getting true null hypothesis.

Which table and graph represent the equation y = 3X?
—————————
a.table B and graph A
b.table B and Graph B
c.table A and graph B
d.table A and graph A
Answer:
d. table A and graph A
Step-by-step explanation:
y=3x
y = 3X is represented by graph B .
y = 3X is represented by table A .
Hence option C is correct .
Given, Equation : y = 3X
Now, to get the values of y substitute x.
Firstly table A:
y = 3X
x = 1 : y = 3
x = 2 : y = 6
x = 3 : y = 9
Thus table A represents the equation .
Next graph B :
Starting point of graph B is origin.
Coordinates of origin : (0,0)
Equation of graph B : y = 3X
Thus graph B represents the equation .
Therefore option C is correct .

A point P os equi distant from R(-2,4) and S(6,-4) and its x co ordinate is twice its Y co ordinate find co ordinates of P
Answer: [tex]P(-4,-2)[/tex]
Step-by-step explanation: Distance between two points is calculated as
[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
Equidistant means the same distance, i.e., the distance between points P and R is equal to the distance between points P and S.
Suppose P's y-coordinate is a. If its x-coordinate is double, then
(x,y) = (2a,a)
Thus
[tex]\sqrt{(2a+2)^{2}+(a-4)^{2}} =\sqrt{(2a-6)^{2}+(a+4)^{2}}[/tex]
Solving
[tex]4a^{2}+8a+4+a^{2}-8a+16=4a^{2}-24a+36+a^{2}+8a+16[/tex]
[tex]5a^{2}+20=5a^{2}-16a+52[/tex]
[tex]-16a=32[/tex]
[tex]a=-2[/tex]
y-coordinate is [tex]-2[/tex], then x-ccordinate is
2a = 2(-2) = [tex]-4[/tex]
Coordinates of point P equidistant for R and S is [tex](-4,-2)[/tex].

Answer:
1500
Step-by-step explanation:
We can required to find the sum which also means the value
Future value= value × [ 1 + rate×time]
2400= value × [1 + 15/100×4]
2400= value × [1 + 0.15×4]
2400= value × [1+0.6]
2400= value × 1.6
Value= 2400/1.6
= 1500
