Hi, kindly help me with how to solve this problem. I've seen some solutions, but I still don't understand :/ A sample of the reading scores of 35 fifth-graders has a mean of 82. The standard deviation of the sample is 15.a) Find the 95% confidence interval of the mean reading scores of all fifth-graders. b) Find the 99% confidence interval of the mean reading scores of all fifth-graders. c) Which interval is larger? Explain why
When I need to determine which standard deviation would give the better grade, what if the z-score is negative such as -.8 and -.4. Wouldn't the .-4 score provide a better grade because it's closer to m=42? The oridinga score is 38 and the mean is 42 but there are two standard deviation scores of 5 (answer was -.8) and 10 (answer was -.4) and I need to decide which one give the better grade.
Suppose a test is given to 20 randomly selected college freshmen in Ohio. The sample average score on the test is 12 points and the sample standard deviation is 4 points. Suppose the same test is given to 16 randomly selected college freshmen in Iowa. The sample average score on the test is 8 points and the sample standard deviation is 3 points. We want to test whether there is a significant difference in scores of college freshmen in Ohio versus Iowa. What is the point estimate for the difference in population means, where difference is defined as (Ohio minus Iowa)?
