A frequenter of a pub had observed that the new barman poured in average 0.47 liters of beer into the glass with a standard deviation equal to 0.07 liters instead of a half a liter with the same standard deviation. The frequenter had used a random sample of 53 glasses of beer in his experiment. Consider the one-sided hypothesis test for volume of beer in a glass: H0​:μ=0.5 against H1​:μ<0.5 Determine the P-value of this test. Round your answer to four decimal places (e.g. 98.7654). P− value =
