Answer:
$2948 and $4030
Step-by-step explanation:
The CI is sample mean +/- s/sqrt(n)
t(0.95,df=63 critical values are |t|>1.669
90% CI is 3489+/-1.669*(2595/8) since sqrt(64)=8
the interval is 541.38
round to 541
the interval is 3489+/-541
($2948,$4030) is the 90% CI for the mean.
First you need to find out how many cm of water that will be saved after brushing your teeth 3 times.
379 x 3 = 1137
Next you need the convert the cm to liters. You do this by dividing the cm total by 1000.
1137 / 1000 = 1.137
So you would save 1.137 liters of water while brushing your teeth 3 times.
Hope this helps!!
