Rx - st = r

Rx = r + st Add st to both sides

Rx - r = st Subtract r from both sides

(Rx - r)/t = s Divide t on both sides ( to isolate s)

$rx-st=r\qquad\text{subtract rx from both sides}\\\\-st=-rx+r\qquad\text{change the signs}\\\\st=rx-r\qquad\text{divide both sides by}\ t\neq0\\\\\boxed{s=\dfrac{rx-r}{t}}$

Find the P- value for the hypothesis test with the standardized test statistic z. Decide whether to reject H 0 for the level of

kkurt [141]

Answer:

Option B) 0.1032; fail to reject $H_0$

Step-by-step explanation:

We are given the following information in the question:

We used two tailed z-test to perform the hypothesis.

$z_{\text{stat}} = -1.63$

Level of significance, α = 0.05

We have to calculate the p-value.

We calculate the p-value from the normal standard z-table.

p-value = 0.1032

Since,

p-value > Level of significance

We fail to reject the null hypothesis and accept it.

Option B) 0.1032; fail to reject null hypothesis

All you need is the double angle identity:

$\cos^2x=\dfrac{1+\cos2x}2$

So we have

$\cos^4x=(\cos^2x)^2=\left(\dfrac{1+\cos2x}2\right)^2=\dfrac{1+2\cos2x+\cos^22x}4$

Apply the identity again to the squared term:

$\cos^4x=\dfrac{1+2\cos2x+\frac{1+\cos4x}2}4=\dfrac{3+4\cos2x+\cos4x}8$
