Answer 1

Solution . using the graph we have to find the area under the Curve ie left twild Now using graph we say that the # data is Mormally distributed hence we use Standard Normal probability table given below Now here 2=0.02 Hence find the value in the table of Normicel probability table which is near to 0.02 and value near to 0.02 is 0.0202 Mow, find row and column Corroespounding to 0.0202 Hence row is -2.0 and Column is 0.05 Therefore Table value corres pounding to 0.0202 is -2.05 Hence we gate - 2.05 when 2=0.02 which is left tailed -d- -2.65 Thank you..!! please like it...
