Answer: 39.308 pounds
Step-by-step explanation:
We assume that the given population is normally distributed.
Given : Significance level :
Sample size : n= 12, which is small sample (n<30), so we use t-test.
Critical value (by using the t-value table)=
Sample mean :
Standard deviation :
The lower bound of confidence interval is given by :-
i.e.
Hence, the lower bound for the 98% confidence interval for the mean yearly sugar consumption= 39.308 pounds
This answer us 16.97
you do square root of 288 and it will give you the answer of 16.97
Option B
The amount in account after 3 years is $ 12444.66
<em><u>Solution:</u></em>
Given that,
$9500 is invested at an interest rate of 9%, compounded continuously
<em><u>The formula for total amount when interest is compounded continuously:</u></em>
Where "p" is the principal
"r" is the rate of interest
"t" is the number of years
In this problem,
p = 9500
t = 3 years
<em><u>Substituting the values we get,</u></em>
Thus amount in account after 3 years is $ 12444.66
