The number of successes and the sample size for a simple random sample from a population are given below. xequals10, nequals50, 95% level a. use the one-proportion plus-four z-interval procedure to find the required confidence interval. b. compare your result with the result of a one-proportion z-interval procedure.

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.

-6 is the correct option from the above given options

150.6

all i did was i multiplied 5.02 by 30
