7. Small newborn seal pups have a lower chance of survival. Suppose that the length of a newborn seal pup is a normal distribution with a mean length of 30.1 inches and a standard deviation of 1.3 inches. a. What is the probability that a newborn pup selected at random will be between 27 and 31 inches long? Include a sketch in your answer. Round to 3 decimal places. 27-31 inches 9:1.3 Normal colf (a7,31,30-1,1.3) M=30.1 = 1.3 0.747 b. Draw a sketch of the normal curve that represents P90, the 90th percentile, then find the seal pup length that represents P90. Round to 1 decimal place. Value -mean Pg 25: Standard deviation EXTRA CRET c. What would be the minimum length of seal pups in the top 2%, the very largest of them? Include a sketch. Round to 1 decimal place.
