A soft-drink machine is regulated so that the amount of drink dispensed is approximately normally distributed with known standar

Vsevolod [243]

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

This is a reasonable decision because the sample size has no effect on the 90% confidence interval

from condition 1 :

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%

for condition 2 :

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 $\frac{std}{\sqrt{n} }$

= 2.25 ± 1.645 $\frac{0.15}{\sqrt{20} }$

= 2.25 ± 0.0335 = ( 2.2835 , 2.2165 )
