The following data were obtained at the same laboratory. Assume 95% confidence level.

Worker A x = 25.8 ng/mL s = 0.65 n = 4 samples

Worker B x = 19.7 ng/mL s = 0.45 n = 6 samples

(Note; x = mean)

Find the pooled standard deviation

Use the t-test to compare the results obtained by the 2 workers.

Use the F-test to compare the standard deviations

Find the pooled standard deviation.

Expert Solution

check the calculations. And check f value from table.

At a confidence level of 95% a confidence interval for a population proportion is determined to be 0.65 to 0.75. If the sample size had been larger and the estimate of the population proportion the same, this 95% confidence interval estimate as compared to the first interval estimate would be A. the same B. narrower C. wider

A confidence interval, at the 95% confidence level, will be used to answer the question, "What is the mean annual salary (in US dollars) of a Tesla car owner?" Data was collected from 36 Tesla owners across the US. The mean annual salary of those 36 Tesla owners was $254000. The standard deviation of ALL Tesla owners is known to be $1057. a) The value at the center of the confidence interval represents what quantity? Choose an option from the list and type its...

Obtain 95% confidence interval in the following studies . Six coins of the same type are discovered at an archaeological site. If their weights on average are significantly different from 5.25 grams then it can be assumed that their provenance is not the site itself. The coins are weighed and have mean 4.73 g with sample standard deviation 0.18 g. Obtain 95% confidence interval for the mean.
