Answer:
Step-by-step explanation:
Given that
Group Group One Group Two
Mean 26.00 23.00
SD 2.00 4.00
SEM 0.40 1.21
N 25 11
where group I represents female servers and group II male servers.
We have to calculate confidence interval for 90% for difference in means
The mean of Group One minus Group Two equals 3.00
df = 34
standard error of difference = 0.993
t critical = 2.034 for 90% df 34
Hence confid. interval at 90%
=Mean diff ±2.034 * std error of diff
= (0.98, 5.02)
Ok for example a sequence is 1 2 3 it is a set of numbers in a corresponding order. So to find a missing number in 2 4 _ 6 8 10, you would look at the numbers that you have, for example 6 8 10, each of them are two apart so is 2 and 4 so the answer would 6! But there are more difficult sequences such as 1 3 5 9 11 13 15 _
You could look at this one and think easy, its 17, but there is a 5 and a 9, those are 4 apart. So every three there numbers there is a 4 number difference while in the others there is a two. So you would say the missing answer is 19!Hope it helps.
