Question 1: testing to see if there is evidence that the proportion of us citizens who can name the capital city of canada is greater than 0.75. state the null and alternative hypotheses. also, state the direction of the test using the following possible sample results: • sample a: 31 successes out of 40 • sample b: 34 successes out of 40 • sample c: 27 successes out of 40 • sample d: 38 successes out of 40 state which of the possible sample results provides the most evidence against the null. briefly explain state which (if any) of the possible results provide no evidence for the alternative. briefly explain

2.83941151 would be the answer you're looking for! : )

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
