Hi
Distribution: normal with µ = 616 and σ = 13
Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus

<u>The heaviest 15% of fruits weigh more than how many grams?</u>

{{{z =blue (x - mu)/blue(sigma)}}} OR {{{blue(sigma)*z + mu=blue (x)}}}
invNOrm(.85) = 1.0364
(1.0364)*13 + 616 = 629.4732gm  
<u>The heaviest 15% of fruits weigh more than  629.4732gm </u>
Wish You the Best in your Studies.
