You are a researcher studying the lifespan of a certain species of bacteria. From a previous study, it was found that the standard deviation was 5.6 hours. You would like to estimate the mean lifespan for this species of bacteria to within a margin of error of 0.45 hours at a 98% level of confidence. What sample size should you gather to achieve a 0.45 hour margin of error?
Answers: 1
is
![n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2](/tpl/images/0901/1187/a50a9.png)
![n = [2.33 } * 5.6}{0.45} ] ^2](/tpl/images/0901/1187/ca366.png)
