Question

Suppose that the life-span of goldfish can be modeled by the Normal Distribution with a mean of 5 years and a standard deviation of 2.3 years. What is the life span of the
90th percentile of goldfish? Interpret this value.
The 90th percentile is 7.95 years. This means that 90% of goldfish will have lifespans less than or equal to 7.95 years.
The 90th percentile is 2.05 years. This means that 90% of goldfish will have lifespans greater than or equal to 2.05 years.
The 90th percentile is 2.05 years. This means that 90% of goldfish will have lifespans less than or equal to 2.05 years.
O The 90th percentile is 7.95 years. This means that 90% of goldfish will have lifespans greater than or equal to 7.95 years.
