What is the standard error for the sample of ducks? show all work. what is the tvalue test stat and critical and t value using a 99 percent CI? show the work for your interval construction.

If you were to sample more ducks to increase sample size for the wingspan, how would the 99% CI change compared to the one calcualted above (ex wide/narrow assume the mean and sd retain same values.

A biologist who studies bird migration was interested in measuring the wingspan of mallard ducks to
understand their flight capability. The biologist trapped 19 mallards from across Tennessee and found that
the duck wingspan had a mean of 90.4 cm and a standard deviation of 6.9 cm. (Use at least 2 decimal places
in your calculations)
