The answer would be 2,569.
I don't know if is completely correct but I got
Students = 613.6
Adults = 324.4
Given:
n = 27, sample size
df = n-1 = 26, degrees of freedom
xb = 11.8, sample mean
s = 2.3, sample standard deviation.
Because population statistics are not known, we should use the Student's t-distribution.
At 99% confidence interval, the t-value = 2.779 (from tables).
The confidence interval is
11.8 +/- 2.779*(2.3/√(27)) = 11.8 +/- 1.23 = (10.57, 13.03)
Answer: (10.6, 13.0) to the nearest tenth
Answer:
The apricots are less expensive per pound.
Step-by-step explanation:
Cost of 1 pound of almonds = 21.98/2
Cost of 2 pounds of almonds = $21.98
So then you have to do 21.98 - 21.98/2. Which equals $10.99
Cost of 1 pound of dried apricots = 26.25/3
Cost of 3 pounds of dried apricots = $26.25
So then you have to do $26.25 - 26.25/3 which = $17.5 then divide that by 2 which equals $8.75.
To find out how much less expensive you have to find the difference, so to do that you have to do $10.99 - $8.75 = $2.24 per pound less expensive.
