Answer:
a) ME= 1.93
b) confidence interval= (19.59,23.45)
Explanation:
a) Sample of customers is 64, population standard deviation is 6 and confidence level is 99%
Sample mean= 21.52
Sample size= 64
Confidence level= 99%
Population standard deviation= 6
Standard error of the mean= 0.75
Z-value= -2.5758 (From Z table)
Interval half width= 1.9319
Margin of error at 99% confidence interval is 1.93 from the output.
b) Confidence interval
Interval upper limit= 19.59
Interval lower limit= 23.45
99% confidence interval is (19.59, 23.45) from the output.
ME= 
= 1.93

Answer:
The nominal value at the end of 17 years = $7,455.34
The real value at the end of 17 years = $2,437.95
Explanation:
Value at the end of 17 years = present value x (1+ interest rate)^t
The nominal value at the end of 17 years = $1,475 x (1.1)^17 = $7,455.34
The real value at the end of 17 years = $1,475 x (1.03)^17 = $2,437.95
It is true that ''In a forecasting model using simple moving average, the shorter the time span used for calculating the moving average, the closer the average follows volatile trends''.
There are three fundamental categories: causal models, time series analysis and projection, and qualitative approaches. The first makes use of qualitative data (such as the judgement of experts) and details about noteworthy occasions of the sort already discussed, and may or may not take historical factors into account.
Although there are many commonly used quantitative budget forecasting tools, in this article we concentrate on the top four techniques: Straight-line, moving average, simple linear regression, multiple linear regression, and straight-line.
The Global Forecast System (GFS) of the National Weather Service and the European Center for Medium-Range Weather Forecast (ECMWF) model are the two most well-known NWP models. The American and European models are other names for them.

Answer:
E. $330 credit to allowance for doubtful accounts
Explanation:
With regards to the above, the adjusting entry on December 31st is computed as;
= [($15,000 - $1,500)× 0.1)]
= $135
1% of the balance less than 30days
= $1,500 × 0.1 = $150
Total = $45 + $135 + $150 = $330
