Assume that a sample is used to estimate a population mean μμ. Find the 95% confidence interval for a sample of size 63 with a mean of 49.8 and a standard deviation of 5.5. Enter your answer as an open-interval (i.e., parentheses) accurate to 3 decimal places.
A research scholar wants to know how many times per hour a certain strand of virus reproduces. He wants to construct the 80% confidence interval with a maximum error of 0.2 reproductions per hour. Assuming that the mean is 6.4 reproductions and the variance is known to be 5.29, what is the minimum sample size required for the estimate? Round your answer up to the next integer.
A research scholar wants to know how many times per hour a certain strand of virus reproduces. He wants to construct the 90 % confidence interval with a maximum error of 0.2 reproductions per hour. Assuming that the mean is 11.9 reproductions and the variance is known to be 5.29, what is the minimum sample size required for the estimate? Round your answer up to the next integer.
Given two independent random samples with the following results: n1=12x‾1=73s1=27n1=12x‾1=73s1=27 n2=12x‾2=102s2=22n2=12x‾2=102s2=22 Use this data to find the 95%95% 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. Step 1 of 3 : Find the point estimate that should be used in constructing the confidence interval.
