Question: Suppose X ~ N (59, 8). Write the Excel function to find the X values associated with the following percentages: Middle 54 percent X upper

SupposeX~N(59, 8). Write the Excel function to find theXvalues associated with the following percentages:

Middle 54 percent

  • Xupper=NORM.INV(0.23,59,8),Xlower=NORM.INV(0.79,59,8)
  • Xupper=NORMS.INV(0.79,59,8),Xlower=NORMS.INV(0.23,59,8)
  • Xupper=NORM.INV(0.77,59,8),Xlower=NORM.INV(0.23,59,8)
