Calculate a 90% for ?, however assume that we do not know ?. Explain how we can workaround this problem. Must include your point estimate, the confidence coeffcient, and the standard error ofX.

C.I = 90%

N = 35

?Xbar = ? = 16477.64

?Xbar = 379.905289

Was the confidence interval successful in capturing the true population mean?

Suppose we are interested in how well people do on a standardized test when they take it for a second time. In a random sample of 400 students who took the test for a second time, students gained an average of X-bar = 12 points. Let’s say that the sample comes from a population with σ = 42. The 95% confidence interval for μ (the mean point gain) is: μ = 12 ± (1.96) (42/√400) = 12 ± 4.12 =...

Assume that a sample is used to estimate a population proportion p. Find the 90% confidence interval for a sample of size 248 with 84 successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. 90% C.I. = _______________________ Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
