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

Solve by factoring. p⁴=-25p²​
3241004551 [841]

Answer:

p=5i

Step-by-step explanation:

(p^(4)=-25p^(2))/p^(2)

p^(2)=-25

Square root both sides

p=5i

i is the square root of -1, so 5i is five times that much.

The square root of a negative number in not real. That is why it is i, and not a number.
