Please can you be specific on what does this imply about the
interpretation of the given interval. As well as how much would 99%
differ from 95% CI.
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 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). A) Find 99% Confidence Interval B) Can you tell how much would it be wider compare to 95% Confidence Interval? Mention all the steps for the both answers.

Question 5. A random sample of 50 bottles of a brand of cough syrup is selected, and the alcohol content of each bottle is measured. Let μ be the mean alcohol content for the population of all bottles of the brand under consideration. The 95% confidence interval estimated from the data is (7.8 μ 9.4). (a) would a 90% confidence interval calculated from the same sample be wider or narrower? Explain. (b) Consider the statement: there is a 95% chance...

a) Approximately 500 students take a particular college statistics course each year. As an exercise, each of the 500 students in the class is given a different random sample of the previous year's 500 final grades (in percentages) and asked to construct a 95% interval estimate of the previous year's overall average. Which of the following statements is correct? About 475 of the confidence intervals will contain the actual overall average for the previous year. It is probable that 475...
