This passge below require critical analysis and breakdown
Moving averages, weighted moving averages, and exponential
smoothing methods are forecasting methods that are used for a time
series with a horizontal pattern. These methods provide a high
level of accuracy for short-range forecasts, such as a forecast for
the next time period and are used to smooth out random fluctuations
in the time series and have a high level of accuracy for
short-range forecast. The moving Average method uses the average...

This passge below require critical analysis and breakdown
Moving averages, weighted moving averages, and exponential
smoothing methods are three forecasting methods that are
appropriate for a time series with a horizontal pattern. These
methods are easy to use and generally provide a high level of
accuracy for short-range forecasts, such as a forecast for the next
time period. “The moving averages method uses the average of the
most recent k data values in the time series as the forecast for...

this passage require Analysis and breakdown
Moving averages is a forecasting method that uses the average
of the k most recent data values in the time series as the forecast
for the next period (Anderson, Sweeney, Williams, Camm, Cochran,
Fry, & Ohlmann). This approach can be used when the company
requires immediately forecasting for a massive volume of data.
Exponential smoothing a forecasting method that uses a weighted
average of past time series values as the forecast; it is a...

All ratios should use year-end totals and not averages and be
compared to its industry average as well as time trend analysis.
Calculate the ratios mentioned in the table below. For the turnover
in days, assume 365 days. Also the debt ratio industry average
given in the case is actually the liabilities-to-asset ratio. Hint:
for Cash flow statement, you have to add back amortization to the
Land, Plant, and Equipment item.
