Drug for Nausea Ondansetron (Zofran) is a drug used by some pregnant women for nausea. There was some concern that it might cause trouble with pregnancies. An observational study was done of women in Denmark (Pasternak et al. 2013). An analysis of 1849 exposed women and 7376 unexposed women showed that 2.1 % of the women exposed to ondansetron and 5.8 % of the unexposed women had miscarriages during weeks 7 to 22 of their pregnancies. a. Was the rate of miscarriages higher with Zofron, as feared? b. Which of the conditions for finding the confidence interval do not hold?

(Round to two decimal places as needed.)
A retail store manager claims that the average daily sales of the store are $1,500.
You aim to test whether the actual average daily sales differ significantly from this claimed value.
You can provide your answer by inserting a text box and the answer must include:
