Step-by-step explanation:
:proportion of male smoker lung deaths is same for the four given tar level categories.
:proportion of male smoker lung deaths is not the same for the four given tar level categories.
Expected frequency=1177/4=294.25
Tar level Observed Freq.(O) Expected Freq.(E) (O-E)^2/E
0-7 107 294.25 120.435
8-14 375 294.25 5.643
15-21 553 294.25 227.533
>=22 183 294.25 42.061
Total= 1177 1177 395.673
Total chi square score=395.673
df=4-1=3
p-value=CHIDIST(395.673,3)<0.001
p-value<0.001,Reject null hypothesis.
There is sufficient evidence that the proportion of male smoker lung deaths is not the same for the four given tar level categories.

Answer:
She does not have enough money to pay back her parents. She needs $3 to be able to do so.
Step-by-step explanation:
If she owes her parents $50 and she has $10 in savings, the her debt to them is only 40$ as 50-10 = 40. When she does chores she eliminates $12 from her debt and now owes them $28 as 40-12 = 28. When she gets $25 for her birthday she sues that to pay them back and 28-25 = $3. Therefore, she still owes them $3.
