Confidence Interval Swetha, who joined the Imperial Bank of Hyderabad as an analyst, is trying to estimate the 95 percent two-sided confidence interval for the average monthly profits of tiny units owned by women entrepreneurs. She asked her assistant Rangaswamy to collect the data from 100 tiny units, selected randomly. Based on the sample average given to her by Rangaswamy, she calculated a 95 percent confidence interval using the population standard deviation, σ, which was obtained from the earlier data...

For this activity, you will be creating a confidence interval for the average number of hours of TV watched. Last semester, my MAT 152 online students asked the question, “How many hours of screen time do you have in a typical week?” Please use the data they collected to answer the following questions. Data: 21, 2, 28, 30, 18, 21, 25, 20, 25, 14, 21, 25, 50, 39, 46, 20, 35, 45, 37, 46 Are there any outliers in this...

Consider the formula used for any confidence interval and the elements included in that formula. What happens to the confidence interval if you increase the confidence level, increase the sample size, or increase the margin of error? Only consider one of these changes at a time. Explain your answer with words and by referencing the formula.

#1.       You are to construct a 99% confidence interval of a normally distributed population; the population standard deviation is known to be 25. A random sample of size 28 is taken; (i) the sample mean is found to 76 and (ii) the sample standard deviation was found to be 30. Construct the Confidence interval. Clearly name the standard distribution you used (z, or t or F etc.) and show work. (10 points)

Suppose you calculate a 95% confidence interval for the difference in population means. The confidence interval contains both negative and positive values. Will a 99% confidence interval based on the same data contain both negative and positive numbers as well? Choose the correct response from the options provided below. Yes. Keeping all other values the same, increasing the confidence level leads to a wider interval which would still include negative and positive numbers. No. Increasing the confidence level leads to...
