Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol ( μ, rho, σ) for the indicat

ed parameter. A psychologist claims that more than 5.8 percent of the population suffers from professional problems due to extreme shyness. Use p, the true percentage of the population that suffers from extreme shyness.
a) H0 : p = 5.8%
H1 : p < 5.8%
b) H0 : p = 5.8%
H1 : p ≥ 5.8%
c) H0 : p = 5.8%
H1 : p > 5.8%
d) H0 : p = 5.8%
H1 : p ≤ 5.8%

Answer:

c) H0 : p = 5.8%

H1 : p > 5.8%

Step-by-step explanation:

At the null hypothesis, we test that the percentage is equal to a certain value. At the alternate hypothesis, we have a test about this percentage, if it is more, less, or different from the tested value.

A psychologist claims that more than 5.8 percent of the population suffers from professional problems due to extreme shyness

At the null hypothesis, we test if the percentage is 5.8%

H_0: p = 5.8\%

At the alternate hypothesis, we test if this percentage is more than 5.8%. So

H_a: p > 5.8\%

This means that the correct answer is given by option c.

The line has the same slope as 7x-y=5 and the same y intercept as the graph 3y-11x=15
scoundrel [369]
7x - y= -5. Standard form is when it is written with x and y on the same side, but x is not negative or a fraction. To find the slope and y intercept, you must change the first two equations to slope intercept. You get y=7x-5 for the first one and y=11/3x+5 for the seccond equation. Take the 5 as your y intercept and the 7 as your slope and you get y=7x+5. Now you need to change it into standard form. When all is said and done, your final answer should be 7x - y = -5.

Find the distance between the points (-5, 0) and (-4, 1).
choli [55]
The formula of a distance between two points A and B is : 

AB=\sqrt{(x_{B}- x_{A})^2 +( y_{B}- y_{A})^2     }

You should this formula by heart.

Then, you just have to apply it ! :D

Here :

x_{A}=-5
y_{A} =0

x_{B} =-4
y_{B}= 1

Therefore :

\sqrt{(-4-(-5))^2+(1-0)^2}
=  \sqrt{1^2+1^2}
= \sqrt{1+1}
= \sqrt{2}

In short, the answer would be the first option : \sqrt{2}.

Hope this helps !
