Question 4

An algorithm is designed to analyze atmospheric pressure readings in hectopascals (hPa) relative to a standard baseline pressure.

threshold ← 1013.25
readings ← [1008.2, 1011.5, 1014.1, 1012.9]
is_anomaly ← False
sum_dev ← 0.0

FOR EACH p IN readings
    deviation ← p - threshold
    sum_dev ← sum_dev + deviation
    IF deviation > 5.0 OR deviation < -5.0 THEN
        is_anomaly ← True
    ENDIF
ENDFOR

mean_deviation ← sum_dev / 4

Select the most appropriate data type for the variable mean_deviation used in this algorithm.
