Problem #5: The breaking strength of yarn used in the production of woven carpet material is normally distributed. A randomsample of 5 specimens of yarn from a production run is measured for breaking strength, and the standarddeviation is found to be 2.9. Also, a confidence interval for the true mean breaking strength u is calculated to be(131.825166, 137.354834). What is the confidence level for this interval?Problem #5:answer as a percentagecorrect to 2 decimals, e.g., 82.50

A sample of size n = 36 is drawn from a population whose standard deviation is σ = 15.6. The sample mean is x = 94.5. Construct a 95% confidence interval.
The director of research and development is testing a new drug. She wants to know if there is evidence at the 0.025 level that the drug stays in the system for more than 370 minutes. For a sample of 7 patients, the average time the drug stayed in the system was 380 minutes with a standard deviation of 21. Assume the population distribution is approximately normal. Step 1 of 6: State the null and alternative hypotheses. Step 2 of 6: Find the value of the test statistic. Round your answer to two decimal places. Step 3 of 6: Specify if the test is one-tailed or two-tailed. Step 4 of 6: Find the P-value of the test statistic. Round your answer to four decimal places. Step 5 of 6: Identify the level of significance for the hypothesis test. Step 6 of 6: Make the decision to reject or fail to reject the null hypothesis.
A simple random sample of size n = 40 is drawn from a population. The sample mean is found to be x = 121.2 and the sample standard deviation is found to be s = 12.6.

A sample of size n=49 is drawn from a popular whose standard deviation is q=4.8. a. Find the margin of error for a 95% confidence interval for "u". b. If the sample size were n=60, would the margin of error be larger or smaller?
A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x, is found to be 115, and the sample standard deviation, s, is found to be 10. (a) Construct an 80% confidence interval about μ if the sample size, n, is 25. (b) Construct an 80% confidence interval about μ if the sample size, n, is 12. (c) Construct a 70% confidence interval about μ if the sample size, n, is 25. (d) Could we have computed the confidence intervals in parts (a)-(c) if the population had not been normally distributed?
Suppose 80 independent measurements are made for the speed of sound with an air temperature of 10 Celsius. The mean of the samples was 338.5 meters per second and the standard deviation was 2.2. Which of the statement below are True? a. Approximately 95% of the sample measurements need to be between 338.5 ± 1.96 * 2.2 for the mean of the sample to be normally distributed. b. Based on this sample, the 95% confidence interval for the true speed of sound at 10C is 338.5±1.96* 2.2/√80 c. The probability that the true speed of sound at 10C is between 338.5±1.96 * 2.2/√80 is 95%. d. The probability that the true speed of sound at 10C is between 338.5±1.65 * sqrt(2.2/80 is over 90%. e. Approximately 90% of the sample measurements were between 338.5±1.65 * 2.2/√80 f. The sample size of 80 is too small to judge the accuracy of the measurements.
A confidence interval is desired for the true mean stray-load loss (Watts) for a certain type of induction motor. Assume that the stray-load loss is normally distributed with =3.3Watts. Situation 3: You take 100 measurements of stray-load loss from induction motors and determine that the mean of your sample is 53.6 Watts. When you calculate the 95% confidence interval for this situation, you get: (52.95 Watts, 54.25 Watts) is a 95% confidence interval for M. Compare this confidence interval to the interval you calculated in Situation 1. They are both 95% confidence intervals, but they have different sample sizes. What effect did sample size have on the interval estimate endpoints? Question 1: 25 sample size, Confidence Interval: (52.3064,54.8936)

The daily wage of a particular industry is normally distributed with a mean of 150 pesos. In a random sample of 144 workers of a very large company in this industry, the mean daily wage was found to be 148 pesos with a standard deviation of 10 pesos. Can this company be accused of paying inferior wages (less than the usual) at α=5%? Which of the following sets of hypotheses should be used in this study? A. Ho: μ = 150 vs. Ha: μ > 150 B. Ho: μ = 150 vs. Ha: μ < 150 C. Ho: μ = 148 vs. Ha: μ > 148 D. Ho: μ = 148 vs. Ha: μ < 148
