Question at position 19 Frank hosts a listening party for his newest album. After the guests listen to his songs, he asks them to rate how much they enjoyed the music. He’s curious if this sample of 64 listeners’ rating of his new album is similar to his previous albums. He knows that the population mean enjoyment for his other albums is μ = 96 (out of 100), with a standard deviation of σ = 4. In order to do that, he first needs to calculate the standard error. Based on the information given, what should he get for the standard error?
