Thats a random scatter. can't see any pattern. so, True.
i need help in that answer too. i was just bout to ask this one
Answer:
83.56/p
Step-by-step explanation:
Let the weight of the players = p
Let the weight of the reserve players = r
Since there 9 players, there weight = 9p
And since there 3 reserve players, there weight = 3r
(9p + 3r) / 12 = 188
9p + 3r = 12 * 188
9p + 3r = 2256
Solve for r
r = 2256 / 27p
r = 83.56/p
the degree of polynomial is 3.
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 )
