What is the slope of a line that is perpendicular to the line whose equation is 2y = 3x - 1? -3 - -
Shalnov [3]

Answer: 2/3x

Step-by-step explanation:

First, you need to simplify your original line to point slope formula. Dividing the whole thing by 2 to get y by itself leaves you with

y = 3/2x - 1/2

Any perpendicular line has the opposite slope to the line it is perpendicular to, so you flip the slope to get 2/3x

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
