We run a linear regression and the slope estimate is 0.5 with estimated standard error of 0.2. What is the largest value of b fo

r which we would NOT reject the null hypothesis that β1=b ? (assume normal approximation to t distribution, and that we are using the 5% significance level for a two-sided test; need two significant digits of accuracy)

Answer:

0.9

Step-by-step explanation:

Y = B0 + B1X

B1 is the slope an from the question the slope estimate is 0.5

S.E= standard error at 0.2

At 5percent Level of significance, the z value for the test is equal to 1.96

We are required to find out the largest value of b for which the null hypothesis would be accepted.

0.5 + 1.96 x 0.2

= 0.892

Approximately 0.9

A lighting designer is finalizing the lighting plan
kykrilka [37]

Answer:

No

Step-by-step explanation:

It depends on the shape of the stage, generally, the stage is cuboidal or cubical in shape, so assuming the stage is cuboidal.

Here, the spotlight has top cover the minimum angle of 90° (for a corner position of the spotlight.

Now, compute how much angles the spotlight can cover.

From its central position, the spotlight can rotate 25° to the left or right, so, angle covered due to rotation is 25°+25°=50°.

As the beam of light from the spotlight can spread 22°.

So, the total angle covered by spotlight= 50° + 22°=72°, which is less than the minimum angle required to cover the entire stage.

Hence, the designer can't use the spotlight to light each of the objects on the stage.

I need help -3x=x-(6-2x)?
USPshnik [31]
<span>Simplifying 3x + 6 = 2x
  Reorder the terms: 6 + 3x = 2x
  Solving 6 + 3x = 2x
  Solving for variable 'x'.
  Move all terms containing x to the left, all other terms to the right.
  Add '-2x' to each side of the equation. 6 + 3x + -2x = 2x + -2x
  Combine like terms: 3x + -2x = 1x 6 + 1x = 2x + -2x
  Combine like terms: 2x + -2x = 0 6 + 1x = 0
  Add '-6' to each side of the equation.
6 + -6 + 1x = 0 + -6
 Combine like terms: 6 + -6 = 0
 0 + 1x = 0 + -6 1x = 0 + -6
Combine like terms: 0 + -6 = -6 1x = -6
 Divide each side by '1'. x = -6
 Simplifying x = -6
</span>so the answer is x =-6

Write an equation of the line that passes through point (-8, – 5) and has the slope m= - 1/4 <br>y=
zmey [24]

Answer:

y= -1/4x + 3

Step-by-step explanation:

y-y1 = m(x-x1)

(-8 {x1}, -5 {y1}, -1/4 [m] )

We'll then replace the letters with the available figures.

y-[-5] = -1/4 (x-[-8])

We are made to know that minus + minus= plus

Minus + plus= Minus

Minus x minus = plus

minus x plus = minus

Therefore, the mathematical setting of this question becomes,

y+5 = -1/4 (x+8)

Multiply everything in the bracket with the outside value

-1/4 x X = -1/4x

-1/4 x 8 = -2

The mathematical setting then becomes,

y+5 = -1/4x + -2 (<em>Note: plus + minus = minus</em>)

so, it becomes

y+5 = -1/4x - 2

The equation is supposed to look like this, y= mx + b

Therefore we add +5 to both sides to cancel out

 y+5 = -1/4x - 2

   +5            +5

+5 cancels out +5 which makes the setting,

y= -1/4x - 2 +5 (<em>-2+5 goes around to become 5-2= 3</em>)

The expression now looks like this

<u>y= -1/4x +3 which is the final answer!</u>

<u />y= -1/4x + 3
