A musicologist is attempting to determine the mean length of modern pop songs. She conducts a sample of 40 songs, and finds a sample mean of 211 seconds., with a standard deviation of 12 secods. Assume that the distribution of lengths of pop songs is nearly normal. Define your variable: O Let p be the proportion of pop song that are seconds long. O Let p be the proprotion of songs in the sample. O Let u be the mean length of the sampled pop songs, in seconds. o Let u be the mean length of pop songs, in seconds.. Create and interpret a 95% Confidence Interval. Round your answers to one decimal place. Select an answer and seconds. What is the margin of error? Round your answer to one decimal place. seconds. According to Google, the mean length of pop songs is 210. What do you think of this claim? O The claim is inside the interval. It must be true. O The claim is inside the interval. It is reasonable. O That claim is not in our interval, We do not believe it.
