V$$Today$\text{'}$s forecast using a$3-$day moving average approach is going to be the average of

$93,90,$ and $95$

$.$

Part $3$

The high temperature for today using a$3-$day moving average $=$

$$

$92\mathrm{.}67$ degrees $($round your response to two decimal$$ places$).$

Part $4$

$$Today$\text{'}$s forecast using a$2-$day moving average approach is going to be the average of

$93$ and $90$

$.$

Part $5$

The high temperature for today using a$2-$day moving average $=$

$$

$91\mathrm{.}50$ degrees $($round your response to two decimal$$ places$).$

Part $6$

MAD is the average of absolute error. For determining the MAD for a forecast developed using a$2-$day moving$$ average, the average will be over

$5$

observations.

Part $7$

The mean absolute deviation based on a$2-$day moving average$=$

$$

$1\mathrm{.}90$ degrees $($round your response to two decimal$$ places$).$

Part $8$

Mean squared error$($MSE$)$ is the average of left parenthesis Actual minus Forecast right parenthesis squared. For a forecast developed using a$2-$day moving$$ average, in this$$ relationship, n$=5.$ The value of Summation from nothing to nothing left parenthesis Actual minus Forecast right parenthesis squared will be

$$

$30\mathrm{.}75$ degrees squared $($round your response to two decimal$$ places$).$

Part $9$

The mean squared error for the$2-$day moving average$=$

$$

$6\mathrm{.}15$ degrees squared $($round your response to two decimal$$ places$).$

Part $10$

MAPE is the mean absolute percent error. For a forecast developed using a$2-$day moving$$ average, yesterday's absolute percent error is

$$

$0\mathrm{.}54\%($round your response to two decimal$$ places$).$
