Investigators collect the following data regarding newborn data weights. They wish to compute a 95% CI for the average weight of newborn. Select the best response regarding computing a 95% t (or z) CI for the average weight.

Select one:

a. Computing a 95% CI for the average weight is appropriate because these are continuous data.

b. Computing a 95% CI for the average weight is appropriate because these data appear to be approximately normally distributed.

c. It is unclear whether computing a 95% CI is appropriate because the data are moderately skewed and the sample size is not known.

d. It is not appropriate to compute a 95% CI because the assumptions are not met. The data are moderately skewed, and the sample size is 10 or less.
