Suppose a firm that produces light bulbs wants to know whether it can say that its light bulbs typically last more than 1500 hours. hoping to find support for their claim, the firm collects a random sample of n = 25 light bulbs and records the lifetime (in hours) of each bulb. the information related to the hypothesis test is presented below. test of h0: f$mu leq f$ 1500 versus h1: f$ mu f$ > 1500 sample mean 1509.5 sample standard deviation 24.27 assuming the life length of this type of lightbulb is normally distributed, what is the p-value associated with this test? place your answer, rounded to 3 decimal places in the blank. for example, .123 would be a legitimate entry.
