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 correct answer is 3/13. Divided both by 5.
15/65
3/13
Answer:
y=8x-3
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
<u>To find the answer, you have to </u><u>multiply each term of the first parenthesis' expression with each term in the next parenthesis' expression.</u><u> Then </u><u>combine like terms</u><u>.</u> So we have:
Answer choice B is right.
That's a 240 degree sector of a 9 inch radius circle. The whole circle has area πr² and we want 240/360 of it.
A = (240/360) π (9²) = 54 π
Answer: 54 π square inches
That's the exact answer. An approximation is
169.646 square inches
