A factory that manufactures bolts is performing a quality control experiment. Each object should have a length of no more than 14 centimeters. The factory believes that the length of the bolts exceeds this value and measures the length of 64 bolts. The sample mean bolt length was 14.08 centimeters. The population standard deviation is known to be factory that manufactures bolts is performing a quality control experiment. Each object should have a length of no more than 14 centimeters. The factory believes that the length of the bolts exceeds this value and measures the length of 64 bolts. The sample mean bolt length was 14.08 centimeters. The population standard deviation is known to be σ=0.23 centimeters. What is the test statistic z? What is the p-value? Does sufficient evidence exist that the length of bolts is actually greater than the mean value at a significance level of α=0.1?
It has long been stated that the mean temperature of humans is 98.6 degrees F. However, two researchers currently involved in the subject thought that the mean temperature of humans is less than 98.6 degrees F. They measured the temperatures of 56 healthy adults 1 to 4 times daily for 3 days, obtaining 250 measurements. The sample data resulted in a sample mean of 98.3 degrees F and a sample standard deviation of 0.9 degrees F. Use the P-value approach to conduct a hypothesis test to judge whether the mean temperature of humans is less than 98.6 degrees F at the alpha equals0.01 level of significance.
The accuracy of a coin -counter machine is gauged to accept nickels with a mean diameter of a millimeters 21.21mm . A sample of 42 buckles was drawn from a reported defective coin counter machine located near school . The sample had a sample mean of 21.21mm and a sample standard deviation 0.012mm test the claim that the mean nickel diameter accepted by this coin-counter machine is greater than 21.21mm. Test at the 0.05 significant level. a) identify the correct alternative hypotheses Ha: u=21.22 u>21.21 u<21.21 b) give all answers to 4 decimal places the test statistic value is using the traditional method, critical value is nased on your answer above do you failed to reject H 0 or reject H0 explain your choice
It has long been stated that the mean temperature of humans is 98.6°F. However, two researchers currently involved in the subject thought that the mean temperature of humans is less than 98.6°F. They measured the temperatures of 50 healthy adults 1 to 4 times daily for 3 days, obtaining 225 measurements. The sample data resulted in a sample mean of 98.3°F and a sample standard deviation of 0.9°F. Use the P-value approach to conduct a hypothesis test to judge whether the mean temperature of humans is less than 98.6°F at the a = 0.01 level of significance. State the hypotheses. Ho: H = 98.6°F H,: H < 98.6°F Find the test statistic, to = (Round to two decimal places as needed.)

A tire company claims that the lifetimes of its tires average 50,000 miles. The standard deviation of tire lifetimes is known to be 5,261 miles. You sample 100 tires and will test the hypothesis that the mean tire lifetime is at least 50,000 miles against the alternative that it is less. Assume, in fact, that the true mean lifetime is 49,545 miles. It is decided to reject Ho if the sample mean is less than 48,894. Find the level and power of this test. 0 Round your answers to four decimal places. Level of the test = Power of the test =
It is said that a person’s height changes from morning to night, possibility in response to gravity compressing the spinal columns and the joints in the legs. The height of 14 persons (an equal number of men and women) were measured in the morning and at night and it was discovered that the average height in the morning was 1.750 m and 1.735 m. The mean change in height was 1.5 cm with a sample standard deviation of 3 cm. Any height change in the human population is known to be distributed normally. Is it correct to say that the true average change in height from morning to night is 2.5 cm with a significance level of 0.1)?
