Aconservationist wants to know if the average water level in horseshoe lake is more than the average water level in swan lake.
1. a sample of 23 observations from horseshoe lake has a mean of 43 meters and a standard deviation of 3.2 meters.
2. a sample of 23 observations from swan lake has a mean of 38 meters and a standard deviation of 2.4 meters. test his hypothesis at α = 0.01.
group of answer choices:
o reject h0; it appears that the average water level in horseshoe lake is more than the average water level in swan lake.
o fail to reject h0; it appears that the average water level in horseshoe lake is not more than the average water level in swan lake.
o not sufficient information to decide

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

probability for j is 1/4

while

a is 1/6

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
