What's the key? A method of analyzing digital music files to determine the key in which the music was written was tested to determine its accuracy. In a sample of 333 pop music selections, the key was correctly identified in 268 of them. In a sample of 369 new age selections, the key was correctly identified in 309 of them. Can you conclude that the method is more accurate for new age music than for pop music? Let p₁ denote the proportion of correctly identified keys in new age music. Use the a=0.05 level of significance. Part: 0 / 4 Part 1 of 4 (a) State the appropriate null and alternate hypotheses. Ho: P₁ (Choose one) ▼ P2 H₁: P₁ (Choose one) P₂ This is a (Choose one) test. Part: 1/4 Part 2 of 4 (b) Find the P-value. Round the answer to four decimal places. P-value= S
