53.305) B. (24.591, 35.563) C. (26.591, 37.563) D. (28.591, 39.563) 34. A simple random sample of size n = 36 is taken from a normally distributed original population. The sample standard deviation iss = 7. Find the 99% confidence interval for the population variance o2. A. (27.453, 98.756) B. (28.453, 99.756) C. (29.453, 100.756) D. (30.453, 101.756)

Determine the minimum sample size required when you want to be 90% confident that the sample mean is within one unit of the population mean and o = 11.3. Assume the population is normally distributed. A 90% confidence level requires a sample size of. (Round up to the nearest whole number as needed.)

Given two independent random samples with the following results: n₂ = 8 x₂ = 124 $2 = 28 = 16 n₁ x₁ = 94 $1 = 16 Use this data to find the 90 % confidence interval for the true difference between the population means. Assume that the population variances are equal and that the two populations are normally distributed. Copy Data Step 1 of 3: Find the point estimate that should be used in constructing the confidence interval.

Estimate the minimum sample size needed to achieve the margin of error E= 0.026 for a​ 95% confidence interval.

Use the given confidence interval to find the margin of error and the sample mean. (13.4,21.6) The sample mean is (Type an integer or a decimal.)

Assume that a sample is used to estimate a population mean. Find the 90% confidence interval for a smaple of size 46 with a mean of 68.5 and a standard deviation of 6.6. Enter the answer as an open-interval (parentheses) accurate to one decimal place (because the sample statistics are reported accurate to one decimal place).

Estimate the minimum sample size needed to achieve the margin of error E=0.013 for a​ 95% confidence interval.

Use the given confidence interval to find the margin of error and the sample mean.   ​(12.6​,22.0​) The sample mean is   ​(Type an integer or a​ decimal.)

Estimate the minimum sample size needed to achieve the margin of error E = 0.026 for a 95% confidence interval. The minimum sample size is (Round up to the nearest integer.)
