Answer:
The confidence interval based on the paired design is wider because there is little variation in mileage between the cars.
Step-by-step explanation:
The sample size randomly collected is matched sample and since the confidence interval is based on the paired design is large and wide. There is small variation between the mileage of the two cars indicating the cars have mileage based on the fuel.
Answer:
I dont really know
Step-by-step explanation:
P(A) = 0.993 is the probability of event A
_
P(A) is the probability of not A (note that I am trying to place a bar over A. I hope you can see it, else it is because the editor did not show it as I intended)
Then, use the fact that the probability of A plus the probability not A is equal to 1:
_
=> P(A) + P(A) = 1
_
=> P(A) = 1 - P(A) = 1 - 0.993 = 0.007
So, the answers are:
_
1) P(A) = 0.07
_
2) Yes, A is unlikely because its probability is very low.
To answer this you need to read the stem and leaf lot and determine how many values were over 28., Or how many were less than or at 28 and subtract it from 30.
There are 10 teams at 28 or less, so 20 teams are above 28.
The number to the left of the | tells us the tens place of the set of number that come after it.
For example 2|4 7 8 stands for 24, 27, and 28.
If 20 out of 30 were above 28 homeruns, then your probability is 20/30 or 2/3 or 0.667.

as cosec theeta is inverse of sin theeta:
so
csc0=1/sin0
and sin0=0 when 0={0.pi,and 2pi}
when 0=0.pi,and 2pi</span>
