Extracted text: Supposed NPC Research Firm found that the randomly selected college students in Lucena City spent an average (u) amount of Php 800.00 during their academic break. Assuming the variable is normally distributed and the standard deviation (o) is Php 120.00, find the value of z (rounded-off to the nearest hundredths) and the percentage P (rounded-off to the nearest tenths) of respondents who spend more than Php 1100.00 (x). (Hint: z= (x-u)/o; to find the percentage given a z, use a z-score table or calculator). P= %
