b) using a 3-month moving average, calculate the forecast for april. the forecast for april is $ 1.74 (round your response to two decimal places). c) calculate the mean absolute deviation based on a 2-month average. the mean absolute deviation based on 2-month moving average of march through april is $ nothing (round your response to three decimal places).

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)
