Problem 6 A machine produces metal pieces that are cylindrical in shape. A sample of these pieces is taken and the diameters are found to be 1.01, 0.97, 1.03, 1.04, 0.99, 0.98, 0.99, 1.01 and 1.03 centimeters. The sample mean and standard deviation for the given data are i-1.0056 and s = 0.0246. Assume normality. (a) Find a 99% confidence interval on the mean diameter (b) Compute a 99% prediction interval...

Anyone help me with these 7 questions?
Questions: Q1. A random sample has been taken from a normal distribution and the following confidence intervals constructed using the same data: (38.02, 61.98) and (39.95, 60.05) (a) What is the value of the sample mean? (b) One of these intervals is a 95% CI and the other is a 90% CI. Which one is the 95% CI? Why? Q2. A civil engineer is analyzing the compressive strength of concrete. Compressive strength...
PLEase do problem 2 For your senior design project one of the problems you had to work on was the yield strength of a steel weld joint created by a robot. Your test 15 weld joints and found they had an average yield strength of 270 MPa with a standard deviation of 25MPa. Give a 95% confidence interval for the true yield strength of the weld joint. (by the way Mpa is megapascals measure of force in metric units. 1MPa...
E is yes or no option!!! Thank you
Suppose you are a researcher in a hospital. You are experimenting with a new tranquilizer. You collect data from a random sample of 10 patients. The period of effectiveness of the tranquilizer for each patient (in hours) is as follows: Hours 3 2.6 2.4 2.8 2.4 2 2 2.4 2.2 2.9 a) What is a point estimate for the population mean length of time. (Round answer to 4 decimal places) b)What must...
thank you for helping me, i appreciate this so much, you are

1. Suppose you have a sample of size 100 with mean 5 and standard deviation 2. Construct a 95% confidence interval for the population mean. 2. For a random sample of 50 measurements on the breaking strength of cotton threads, the mean breaking strength was found to be 210 grams and the standard deviation 18 grams. Calculate a 90% confidence interval for the true mean breaking strength of cotton threads of this type.
