Bass: The bass in Clear Lake have weights that are normally distributed with a mean of 2.6 pounds and a standard deviation of 0.9 pounds.
Thank you for the opportunity to help you with your question!
We have the mean ,m=2.6 and standard deviation ,d=0.9
a)We have to find the minimum value of x such that P(x<k)=.8
So the z score corresponding to probability=0.8,from the normal distribution table is .8416
b)The top .5% means the minimum value is the maximum for the probability value 1-.5% =.995
The z score=2.5758
