![Confidence Interval for One Population Mean
In 1903, a paper published by Abigail Camp Dimon, discussed the
effect of environment on the shape and form of two sea snail
species. Nassa obsoleta and Nassa trivittata. One of the variables
that Dimon considered was the length of the shell. A random
sample of 300 N. trivittata specimens was selected. The average
shell length for the sample was 15.9 mm., with a standard
deviation of 2.89 mm.
Find the 90% confidence interval for the average shell length of
all N. trivittata sea snails.
What is the standard error used to calculate this interval? Round
to the 1,000ths place.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F201694a0-b5bc-497a-8720-4da5ec1207be%2F8913be92-1b73-4df3-a6da-c8a011459904%2Fy7gtbqh_processed.png&w=3840&q=75)
