A hypothesis will be used to test that a population mean equals 10 against the alternative that the population mean is more than 10 with known Ï. What is the critical value of z-score for the following significance levels?A) 0.01
B) 0.05
C) 0.10

Answers

Answer 1
Answer:

Answer:

A) 2.58

B) 1.96

C) 1.65

Step-by-step explanation:

A hypothesis used to test that

H_o : \mu  = 10

against the alternatives H1 : \mu not equal to 10

if null hypothesis is true, then distribution of test statics follow

Zo = (\bar x - \mu)/((\sigma)/(√(n)))

for two sided alternatives  hypothesis ( H1: \mu \neq 7), then P value is

P = 2[1- \phi(\left | Zc \right |)]                          (1)

a)significance level  \alpha = 0.01

from 1 eq we get

\pi (\left | Zc \right |) = P(Zo<\left | Zc \right |) = 1 - (0.01)/(2)  = 0.995

Therefore  \left | Zc \right | = 2.58    FROM Z TABLE

B) significance level  \alpha = 0.05

from 1st equation we get

\pi (\left | Zc \right |) = P(Zo < \left | Zc \right |) = 1 - (0.05)/(2)  = 0.975

Therefore  \left | Zc \right | = 1.96    FROM Z TABLE

C) significance level  \alpha = 0.10

from 1 eq we get

\pi (\left | Zc \right |) = P(Zo<\left | Zc \right |) = 1 - (0.10)/(2)  = 0.95

Therefore  \left | Zc \right | = 1.65    FROM Z TABLE

What is an equation in point-slope form of the line that passes through (-7,1) and (-3, 9)

Answers

Step-by-step explanation:

let eqn be y - y1 = m(x - x1)

m = (9 - 1)/(-3 - (-7))

m = 2

sub (-7, 1):

y - 1 = 2(x + 7)

therefore, the equation is y - 1 = 2(x + 7)

What is -9/20 as a decimal and as a percent?

Answers

Decimal: -0.45 percent:-45%
To find out what a fraction as a decimal would be, you simply need to divide the numerator by the denominator.

(-9)/(10) = -9/10=-0.9

Now to find the percent.
To find a percentage based off of a decimal, we can either multiply the decimal by 100, or (my personal shortcut) just shift the decimal point over two places to the right.

-0.9 = -90%

which is all we need to know.

(-9)/(10) written as a decimal and a percent is -0.9 and -90% respectively.
Hope that helped! =)

Which expression can be used to determine the reference angle for an angle, x, measuing 150 degrees

Answers

Answer:

see explanation

Step-by-step explanation:

150° is in the second quadrant.

To find the reference angle in the first quadrant subtract from 180°

reference angle = 180° - 150° = 30°

Answer:
