Researchers wish to carry out a test of the null hypothesis that the mean of a certain population is 760 against a two-sided alternative hypothesis.  In their situation, they (somehow) happen to know the population standard deviation.  They feel comfortable assuming normality for this population, and carry out a Z test.  They draw a sample of 48 individuals from this population, and find a Z test statistic of 0.40.  What is the p-value of the test? (Give your numeric response to at least 3 decimal places.  Give only your numeric response, and not any extra characters or symbols.)
