The 90% confidence interval for the difference in the population proportions will be :-
4v+9<=5
4v<=5-9
4v<=-4
v<-4/4
v<=-1
-3v>=-6
v<=-6/-3
v<=2
the answer is(-1 or 2)
Answer:
11:45 AM
Step-by-step explanation:
We have that in one hour the body temperature decreased
went down in
81.7 - 80.2 = 1.2
i.e. 1.2 degrees.
Normal body temperature is 98.6 degrees.
The difference between normal and 11 pm is 98.6-81.7 = 16.9
i.e. 16.9 degrees
now to know how much it decreases every hour:
16.9/ 1.5 = 11.26, that is 11 hours and 15 minutes (1/4 of an hour)
If that was 11:00 PM - 11:15 minutes, the murder was at 11:45 AM
