A journal article reports that a sample of size 5 was used as a basis for calculating a 95% CI for the true average nat- ural frequency (Hz) of delaminated beams of a certain type. The resulting interval was (229.764, 233.504). You decide that a confidence level of 99% is more appropriate than the 95% level used. What are the limits of the 99% interval?

Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.

Can you help me with this question

A journal article reports that a sample of size 5 was used
as a basis for calculating a 95% CI for the true average nat-
ural frequency (Hz) of delaminated beams of a certain

decide that a confidence level of 99% is more appropriate
than the 95% level used. What are the limits of the 99%
interval? [Hint: Use the center of the interval and its width
to determine x and s.]

The speed of light is measured 25 times by a new procedure. The 25 measurements are recorded, and show no trend or pattern. The investigators work out the average and SD of the 25 measurements; the average is 299,789.2 kilometers per second and the SD is 12 kilometers per second. (Assume the Gauss model, with no bias.) It is assumed that all units are kilometers per second. Find an approximate 95%-confidence interval for the speed of light. Enter numeric answers for the lower and upper endpoints of the interval here; be sure to show your work. (a) The 95% confidence interval for the speed of light is to . (b) Now the investigators measure the speed of light a 26th time by the same procedure, and get 299,781 kilometers per second. Is this a surprising result? Answer yes or no, and explain your reason.
