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.
Answer:

Answer:
<h2>- 417</h2>
Step-by-step explanation:
n - integer
The sum of n and 181 is equal to -236:
n + 181 = -236 <em>subtract 181 from both sides</em>
n + 181 - 181 = -236 - 181
n = -417
Answer:
Circumference= 44 in
Area= 154 in²
Step-by-step explanation:
Radius
= diameter ÷2
= 14 ÷2
= 7 in
Circumference of circle
= 44 in
Area of circle
= 154 in²
