A blue whale is the largest marine mammal. A random sample of 10 blue whales had a mean lung capacity of 5,000 liters and a standard deviation of 600 liters. Find the lower bound of a 95% confidence interval of the lung capacity (round off to the nearest integer).Assume normal population.

i do not know the answer

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
