HW 5: Continuous Random Variables Score: 0/28 0/28 answered Question 28 Progress saved Done 8 0/1 pt 318 ( A researcher is studying voice frequencies. He is working with a group of male non-native English speaker who are learning English. For this group of speakers, the distribution of fundamental frequencies while speaking English (the frequency of the natural speaking voice) has a mean of 125-Hz and a standard deviation of 14-Hz. The distribution of fundamental frequencies is nearly normally distributed. Find P45, which is the frequency separating the lowest 45% fundamental frequency from the higheest 55%. P45 = -Hz Enter your answer as a number accurate to 1 decimal place. Submit Question
