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)
the answer is multiply the current term by 2 and add 1 to find the next term.
2/16
BC there are 2 red marbles out of 16 marbles in total
Let books =x and games =y
2x+2y=26
4x+1y=28
If you solve for x and y, x=5 and y=8
