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.
Base - i cant tell if it’s multiplication or a decimal but if it’s a decimal base is 3.4 if it’s multiplication 12
height - 3.52
area - 1/2 x 3.4(might be 12) x 3.52 = 5.984
