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)

Answer:
1,185.6 in.
Step-by-step explanation:
volume of the triangular prism = base area x height
the base in the shape of a triangle
area of a triangle = 1/2 x base x height
1/2 x 12 x 10.4 = 62.4 in²
volume = 62.4 x 19 = 1185.6 in
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
Here is my work for the problem. Hope this helps!
