6. Calculate the 90% confidence interval for the difference of the average number of fireflies caught in a 15-minute interval before 9pm and the average number of fireflies caught in a 15-minutes interval after 9pm. Show your work!

-1.193 <    > 4.443

Step-by-step explanation:

1.625 -1.895 *4.206712/sqr 8

1.625 -  <  1.625 +    

-1.193 <  U{d}  > 4.443

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.

damm bro the struggle
