A 95% confidence interval for a population mean is (28,35). can you reject the null hypothesis?
considering the standard deviation is 35, thats a pretty big deviation. if you were to be 95% confident, you would have to go out 2 standard deviations which would be insignificant which would mean that the sample mean could be from -42 to 98 which is too large of an area to be precise about a population mean. reject the null hypotheses as 95% confidence interval.
