It's known as the Hum, a steady, droning sound heard in places all around the world. It is a lowfrequency, annoying, throbbing, unexplained sound. It seems to be louder at night and indoors, and approximately 2% of the people living in any given Hum-prone area can hear the sound.
To determine if more people are affected by the Hum, a random sample of 1300 adults in Taos, New Mexico, was obtained, and 24 reported that they regularly hear the noise. Is there any evidence to suggest that the proportion of adults in this area who hear the Hum has changed? Use a = 0.05 and use the p value associated with this hypothesis test to draw a conclusion.
