Question 4 For each normal distribution below, calculate the required cut off (rounded to four decimals): a) For X ~ N(a = 5, 0 = 1.1), calculate the cut-off for which 18%% of values is smaller than the required value: b) For X - N(p =12, o = 3), calculate the cut off for which 34% of values is smaller than the required Value! c) For X - N(( 21, o = 7.5), calculate the cut-off for which 48% of values is larger than the required value
