Calculate the p-value for the following conditions and determine whether or not to reject the null hypothesis. a) one-tail (upper) test, z subscript pequals2.12, and alphaequals0.10 b) one-tail (lower) test, z subscript pequalsnegative 1.32, and alphaequals0.05 c) two-tail test, z subscript pequalsnegative 1.56, and alphaequals0.05 d) two-tail test, z subscript pequals2.37, and alphaequals0.02

a) reject the null hypothesis

b) not reject the null hypothesis

c) not reject the null hypothesis

d) reject the null hypothesis

Step-by-step explanation:

a) one-tail (upper) test, z Subscript p equals 2.12, and alpha equals 0.10

Since p(z)=0.017 < 0.10, the result is significant.

b) one-tail (lower) test, z Subscript p equals negative 1.32, and alpha equals 0.05

Since p(z)=0.093> 0.05 the result is not significant.

c) two-tail test, z Subscript p equals negative 1.56, and alpha equals 0.05

Since p(z)=0.119>0.05 the result is not significant.

d) two-tail test, z Subscript p equals 2.37, and alpha equals 0.02

Since p(z)= 0.018<0.02 the result is significant.

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)
