Please solve part a, c & e The song-length of tunes in the Big Hair playlist of a Statistics professor's mp3-player varies from song to song. This variation can be modeled by the Normal distribution, with a mean song-length of μ=4.25 minutes and a standard deviation of σ=0.7 minutes. Note that a song that has a length of 4.5 minutes is a song that lasts for 4 minutes and 30 seconds.While listening to a song, the professor decides to shuffle the playlist, which means the mp3-player is to randomly pick a song within this particular playlist, and play this next.If using/working with z-values, use three decimals.(a) What is the probability that the next song to be played is between 3.5 and 4.95 minutes long? Answer to four decimals. __________ (b) What proportion of all the songs in this playlist are longer than 5 minutes? Use four decimals in your answer. 0.142 (c) 10% of all the songs in this playlist are at most how long, in minutes? Enter your answer to two decimals, and…
