Question

**Bass - Samples:** The bass in Clear Lake have
weights that are normally distributed with a mean of 2.2 pounds and
a standard deviation of 0.5 pounds. Suppose you catch a
*stringer* of 6 bass with a total weight of 16.3 pounds.
Here we determine how *unusual* this is.

(a) What is the mean fish weight of your catch of 6?
**Round your answer to 1 decimal place.**

pounds

(b) If 6 bass are randomly selected from Clear Lake, find the
probability that the mean weight is greater than the mean of those
you caught. **Round your answer to 4 decimal
places.**

(c) Which statement best describes your situation?

This is not particularly unusual because the mean weight of your fish is only 0.5 pounds above the population average.This is unusual because the probability of randomly selecting 6 fish with a mean weight greater than or equal to the mean of your stringer is less than the benchmark probability of 0.05.

Answer #1

a) = 16.3/6 = 2.7

b) P( > 2.7)

= P(( - )/() > (2.7 - )/())

= P(Z > (2.7 - 2.2)/(0.5/))

= P(Z > 2.45)

= 1 - P(Z < 2.45)

= 1 - 0.9929

= 0.0071

c) This is unusual because the probability of randomly selecting 6 fish with a mean weight greater than or equal to the mean of your stringer is less than the benchmark probability of 0.05.
