For Q1 of 2018, a group of 158 mutual funds had a mean return of 4.6 percent with a standard deviation of 4.5. A histogram shows the returns are approximately Normally distributed. Use the 68-95-99.7 rule (not JMP) to answer the following questions (answer as a percentage, to 1 decimal): (a) What % of mutual funds have a return greater than 4.6? % (b) What % of mutual funds have a return between -4.4 and 13.6? % (c) What % of mutual funds have a return between -8.9 and 18.1? % (d) What % of mutual funds have a return less than 0.1 or greater than 9.1 (i.e., outside the interval)? %
