10. In the past, a machine has produced washers having a thickness of 0.050 inch (in).To determine whether the machine is in proper working order, a sample of 10washers is chosen, for which the mean thickness is 0.053 in and the standarddeviation is 0.003 in. Test the hypothesis that the machine is in proper workingorder, use significance level of 0.05.a) State the hypothesesb) State the level of significancec) State the decision rule (Sampling distribution)d) Calculate the test statistice) State the critical regions, decision and the conclusion

An expert at the Icelandic Meteorological Office is tasked with investigating whether the air quality in the capital area is in accordance with health protection limits. According to them, dust particles should not amount to more than 50 micrograms per cubic meter. The expert collects readings from around the town between 9 and 10 in the morning a. State and perform a one-sided hypothesis test (at a 2% level of significance) about whether the population mean is greater than 50 micrograms. NOTE that the Norwegian Meteorological Agency assumes that the air quality is acceptable unless there is strong evidence that this is not the case. b. Show the result of the test in a picture. What does the result tell you about the sampling distribution of the sample mean? c. What is the p-value and what does it tell you? Show it in the picture you made in part b d. Draw the power function of the hypothesis test e. The measuring devices that are used to measure air quality can be problematic, so…
A sample of 900 members is found to have a mean of 3.47 cm. Can it be reasonably regarded as a simple sample from a large population with mean 3.23 cm. and standard deviation 2.31 cm.? Test at 5% and 10% level of significance.
A manufacturer must test that his bolts are 4.00⁢cm long when they come off the assembly line. He must recalibrate his machines if the bolts are too long or too short. After sampling 169 randomly selected bolts off the assembly line, he calculates the sample mean to be 4.07⁢cm. He knows that the population standard deviation is 0.45⁢cm. Assuming a level of significance of 0.02, is there sufficient evidence to show that the manufacturer needs to recalibrate the machines?
The health of employees is monitored by periodically weighing them in. A sample of n = 54 employees has a mean weight of x̄ = 190 lb. Assuming that σ = 25 lb, use a 0.01 significance level to test the claim that the population mean of all such employees weights is less than 200 lb. Null Hypothesis, H0 Alternative Hypothesis, H1 Test Statistic, z P-value Significance level Conclusion
The mean factory overhead per employees in goods-producing industries is currently $4.57. Suppose a sample of 25 employees from a manufacturing industry showed a sample mean of $3.89 per hour. Assume the sample standard deviation of $.40 per hour. At a .05 significance level, can we conclude the mean factory overhead in the manufacturing industry differs from the population mean in the good-producing industries? Show the six steps of hypothesis testing.
The mean salary of federal government employees on the General Schedule is $59,593. The average salary of 34 state employees who do similar work is $59,070 with =σ $1500. At the 0.10 level of significance, can it be concluded that state employees earn on average less than federal employees? State the hypotheses and identify the claim with the correct hypothesis.
A productionn line operattes with a mean fillling weight of 16 oz per conntainer. Over-filling or under-filling presents a serious problem and reqquires the operator to shut down the production line to readjust the filling mechanism. A quality control inspector selects a sample of 30 itemms every hour and makes the deccision of whether to shutt down the line for readjjustment at that time. Supppose that the most recent sample returns a mean of 15.82 oz and a sample standard deviation of 0.8 oz. Assume the significance level (α) is 5%. A.Formulate the null and the alternative hypotheses: Null: mu ≥ 16; Alternative: mu < 16 Null: mu = 16; Alternative: mu ≠ 16 Null: mu ≤ 15.82; Alternative: mu > 15.82 Null: mu ≤ 16; Alternative: mu > 16 Null: mu = 15.82; Alternative: mu ≠ 15.82 Null: mu ≥ 15.82; Alternative: mu < 15.82 B.

A random sample of 100 pumpkins is obtained and the mean circumferenceis found to be 40.5 cm and standard deviation 1.6 cm. Use a 0.05 significance level to test the claim that the mean circumference of all pumpkins is equal to 39.9 cm.
According to a union agreement, the mean income for all senior-level workers in a large service company equals $500 per week. A representative of a women's group decides to analyze whether the mean income μ for female employees matches this norm. For a random sample of nine female employees, y=$410 and s=90 a)Test whether the mean income of female employees differs from $500 per week. Include assumptions, hypotheses, test statistic, and P-value. Interpret the result.
4) State University uses thousands of fluorescent light bulbs each year. The brand of bulb it currently uses has a mean life of 760 hours. A competitor claims that its bulbs, which cost the same as the brand the university currently uses, have a mean life of more than 760 hours. The university has decided to purchase the new brand if, when tested, the evidence supports the manufacturer's claim at the .01 significance level. Suppose 92 bulbs were tested with the following results: Mean = 778 hours and standard deviation 91 hours. Use the data to conduct a test of hypotheses
A sample of 900 members is found to have a mean of 3.47 cm. Can it be reasonably regarded as a simple sample from a large population with mean 3.23 cm. and standard deviation 2.31 cm.? Test at 5% and 10% level of significance. Also write objective ,null and alternate hypothesis.
