%
X: The bass in Clear Lake have weights that are normally distributed
a sample of size (n) 3 will follow normal distribution with;-
sample mean = 2.3
sample sd =
the probability that all randomly caught groups of 3 bass should weigh between 2.0 and 2.5 pounds be:-
[ in any blank cell of excel type =NORMSDIST(0.57735) press enter
in any blank cell of excel type =NORMSDIST(-0.86603) press enter]
the percentage of all randomly caught groups of 3 bass should weigh between 2.0 and 2.5 pounds be:-
= (0.525*100)%
= 52.5 %
