- Confidence interval for a population standard deviation
A random sample of 15 headache relief pills shows a standard deviation of .8% in the concentration of the active ingredient. Find a 90% confidence interval for the population standard deviation for these pills. Assume that the underlying population distribution of the concentration of the active ingredient is normal. Note: given these small values, use .8, not .008, in your calculations. (Round to 2 decimal places.)

Using Excel, find the value of the 95% confidence interval for a single sample using both the z variable and the student's t-distribution where the mean is 10.00 with a standard deviation of 0.50. When calculating the confidence interval for the z-value, assume any value of n is a large sample, and when calculating the confidence interval for the for the student's t-distribution, assume any value of n is a small sample. Compute the confidence intervals for: a. n 50...

Using confidence intervals to determine how many samples you’ll need to collect so the average voltage will be within the desired accuracy. This will take some assumptions and some work. So, here goes: The confidence interval (CI) equation is: Assume that the voltage you are measuring has a true mean (of course we don’t know the actual mean or true value, but that’s OK) of approximately 1 volt. Next, suppose you desire to know your average () vs “true” value...

As with the confidence intervals, we will be assuming the two population standard deviations are equa but unknown. Thus, we will need to calculate the pooled standard deviation to use in our test statistic. Dur typical hypothesis test would be of the form H:44-42 = 8vs. H:4,-4, 78This is a two side test because the alternative is not equal. (H:14-4, <8, or H:44 - H2>, are also possible. Our test statistic is I X - X₂-8...

This problem demonstrates how to calculate the confidence interval for a population proportion. After, you will be asked to redo the calculations (with small variations). A survey was conducted to determine how many people were in favor of a proposed law to criminalize texting while driving. Response options included strongly disagree, disagree, neither agree or disagree, agree, and strongly agree. The survey asked a random sample of 800 18- to 25-year-olds, and 648 indicated agreeing or strongly agreeing with the...
