Complete Question
In a random sample of 13 microwave ovens, the mean repair cost was $90.00 and the standard deviation was $15.20. Using the standard normal distribution with the appropriate calculations for a standard deviation that is known, assume the population is normally distributed, find the margin of error and construct a 98% confidence interval for the population mean u. A 98% confidence interval using the t-distribution was (78.7,101.3). Compare the results. The margin of error of u is
Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The sample is 
The sample mean is 
The standard deviation is 
The lower limit of the 98% confidence interval is 
The upper limit of the 98% confidence interval is 
Generally the margin of error is mathematically represented as

=> 
=>

Answer:
The amount at the end of second quarter is $1842.704
Step-by-step explanation:
Given as :
The principal in saving account = $1640
The rate of interest = 6 % compounded quarterly
The time period = 6 months
Now,<u> from compounded method</u>
The amount at the end of first quarter =
= principal + 6 % of principal
I.e
= $1640 + 6 % × $1640
Or,
= $1640 + $ 98.4
∴
= $1738.4
Again ,
The amount at the end of second quarter =
=
+ 6 % of
I.e
= $1738.4 + 6 % × $1738.4
Or,
= $1738.4 + $104.304
∴
= $1842.704
So, The amount at the end of second quarter =
= $1842.704
Hence , The amount at the end of second quarter is $1842.704 Answer
Since we have 2 zeros we can take them off and add them back on when we are done.
5 goes into 45 9 times.
now lets add the two zeros back on
900
5 goes into 4500 900 times
