Question

I post this question earlier. How did they find 6.2? Can you detailed the calculations? Thanks

A 95% confidence interval obtained from a sample of 100 outpatients for the true population mean normal mean systolic blood pressure is given by (114 mmHG, 120 mmHG) . Provide a correct interpretation of this interval. Can you think of other interpretations that would also be correct? This confidence interval came from a single sample, would we get the same interval if we obtained a different set of 100 patients? What does this imply about your interpretation of the given interval? . If we wanted a 99% confidence interval instead, can you tell whether it would be narrower or wider? Can you tell by how much?
