A 2017 Raihan et al. study investigated the prevalence of handwashing among children in Bangladesh. As part of this study,
a multifacted survey was sent to the parents of children from Bangladesh. The data provided in the file represent survey
responses from the parents of 10,478 Bangladeshi children regarding whether the children use soap when bathing.
Assume that the data were obtained from a simple random sample of all parents of Bangladeshi children. Suppose the
researchers wish to construct a 95% z-confidence interval for the proportion of children from Bangladesh who use soap
when bathing
Calculate the lower and upper limits of this confidence interval. Do not use a continuity correction. Please specify your
answers to four decimal places. If the requirements for a z-confidence interval are not met, leave both limits blank and
answer the multiple choice question.
