please display the answer in clear decimal format Assuming that the population is normally distributed, construct a 95% confidence interval for the population mean, based on the following sample size of n = 7. 1, 2, 3, 4, 5, 6, and 15 In the given data, replace the value 15 with 7 and recalculate the confidence interval. Using these results, describe the effect of an outlier (that is, an extreme value) on the confidence interval, in general. Find a 95%...
If X-77, σ:8, and n-65, construct a 99% confidence interval estimate of the population mean, μ (Round to two decimal places as needed.)
If X(mean) = 68 If σ = 11, and n = 67, construct a 95% confidence interval estimate of the population mean, μ.
Construct the confidence interval for the population mean μ. 0.90, x-8.1, σ 0.8, and n-60 A 90% confidence interval for μ is (DD-Round to two decimal places as needed.)
Construct the confidence interval for the population mean μ cz 0.90, x-9.6, σ 0.4, and n 51 A 90% confidence interval for μ is (LL) (Round to two decimal places as needed.)
find z sc Construct the confidence interval for the population mean μ 0.95, x 5.2, σ 0.4, and n 58 A 95% confidence interval for μ is D (Round to two decimal places as needed)
Also, help on If X= 101, σ= 6, and n = 69, construct a 95% confidence interval estimate of the population mean, μ. (Round to two decimal places as needed.) lf you want to be 95% confident o estimating he population mean o within a samping error o ± 3 and the standard deviation s assumed to be 12 at sample Size required The sample size required is (Round up to the nearest integer.)
The population of Mosquito has an unknown mean lifespan μ with standard deviation σ = 0.55 days. A) A sample of 23 mosquito has a mean lifespan of 6.5 days. Construct a 87 % confidence interval to estimate the mean lifespan μ of the mosquito population. Round to 4 decimal places.) The interval: 6.5 (Round E to 2 decimal places) The interval in traditional format: ( B) For the same sample of 23 mosquito with mean lifespan of 6 5...
