(b)or
(d)of '69201 of this Chapter, the amount of alcohol in the person's blood at the time of the test as shown by an analysis of that person's blood or breath shall give rise to the following presumptions affecting the burden of proof:
(1)If there was at that time less than eight onehundredths of one percent (0.08%) by weight of alcohol in the person's blood, that fact shall not give rise to any presumption that the person was or was not under the influence of an alcoholic beverage, but the fact may be considered with other competent evidence in determining whether the person was under the influence of an alcoholic beverage at the time of the alleged offense.
(2)If there was at that time eight one-hundredths of one percent (0.08%) or more by weight of alcohol in the person's blood, it shall be presumed that the person was under the influence of an alcoholic beverage at the time of the alleged offense.
