Round the endpoints of the final intervals correctly to two decimal places and clearly label and list these three intervals in your document as shown below: 68% interval (lower value, upper value) 95% interval (lower value, upper value) 99.7% interval (lower value, upper value)Explanation / Answer
1)as 68% values are 1 std deviation away from meam
68% interval =(70.20-3.01 ; 70.20+3.01) =(67.19 ; 73.21)
2)
95% values are 2 std deviation away from meam
95% interval =(70.20-2*3.01 ; 70.20+2*3.01) =(64.18 ; 76.22)
3)
99.7% values are 3 std deviation away from meam
99.7% interval =(70.20-3*3.01 ; 70.20+3*3.01) =(61.17 ; 79.23)
