Answer:
This is a reasonable decision because the sample size has no effect on the 90% confidence interval
Step-by-step explanation:
90% confidence interval
larger sample size = 20
condition : sample mean ( x-bar ) is the same for both samples
<em>This is a reasonable decision because the sample size has no effect on the 90% confidence interva</em>l
<u>from condition 1 :</u>
Amount of drink dispensed is normally distributed with known standard deviation , given a random sample of n drinks and the sample mean at a confidence interval of 90%
<u>for condition 2 :</u>
sample size = 20
mean = 2.25 ( assumed value )
std = 0.15 ( assumed value )
Z = 1.645 ( Z-value )
determine the 90% confidence interval
= mean ± z
= 2.25 ± 1.645
= 2.25 ± 0.0335 = ( 2.2835 , 2.2165 )
Area of Trapezoid
where B = larger base, b = smaller base, and h = height.
For this trapezoid, you have
B = 10 + 7 + 7 = 24
b = 10
h = 9
where B = larger base, b = smaller base, and h = height.
For this trapezoid, you have
B = 10 + 7 + 7 = 24
b = 10
h = 9
