Does standard atmospheric pressure correspond to the normal air pressure at sea level.

Yes

Explanation:

Standard temperature and pressure conditions are defined as 1 atm pressure and 273.15 K. On the other hand, standard ambient temperature and pressure conditions are defined as 1 atm pressure and 298.15 K.

Notice, however, that the only change between them is in temperature.

In any standard conditions, the standard atmospheric pressure is equal to 1 atm.

At sea level, the atmospheric pressure is also equal to 1 atm.

Therefore, we may conclude that the standard atmospheric pressure is equivalent to the normal air pressure at sea level. With an increase in altitude, however, the atmospheric pressure decreases.
