Chinovac Labs tried a new vaccine on 164 randomly selected individuals. From the experiment, it was determined that 120 of them developed immunity. Calculate a 95% confidence interval for the proportion p of individuals in the population for whom the vaccine would help. What is the lower bound of this interval? Note: Write your answers in decimal form and round it to 4 decimal places.
