If a hypothesis is rejected at a 5% level of significance, it . a. will always be rejected at the 1% level b. will never be tested at the 1% level c. will always be accepted at the 1% level d. may be rejected or not rejected at the 1% level

d

step-by-step explanation:

the solution is in the picture

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.

homozygous. one is homozygous, while two is heterozygous.
