The weights of 2-in-1 thirteen inch laptops are normally distributed with an average of 3.19 Ibs (pounds) and a standard deviation of 0.55 Ibs. Sixty (60) percent of this type of laptop weigh more than x Ibs. Which of the following Excel commands can be used to calculate the value of x? O = NORM.INV ( 0,4 ; 3,19; 0,55; TRUE) O = NORM.DIST (0,6 ; 0,4; 3,19 ; 0,55; FALSE) O= NORM.INW (0,6 ; 3,19; 0,55 ) O= NORM.INV ( 0,4 ; 3,19 ; 0,55 ) O = NORM.INV ( 0,4 ; 3,19 ; SQRT(0,55) ) If a random sample of 15 of these laptops is selected, what is the probability that their average weight is less than 3.45 Ibs?

Sixty (60) percent of this type of laptop weigh more than x Ibs. Which of the following Excel commands can be
used to calculate the value of x?
ag question
O = NORM.INV (0,4 ; 3,199; 0,55 ; TRUE )
O = NORM.DIST (0,6; 0,4 ; 3,19 ; 0,55 ; FALSE )
O = NORM.INV (0,6; 3,19; 0,55 )
O = NORM.IN (0,4; 3,19 ; 0,55 )
O = NORM.INV (0,4 ; 3,19 ; SQRT(0,55) )
If a random sample of 15 of these laptops is selected, what is the probability that their average weight is less than
3.45 lbs?
