An administrator at a rural college claims that the proportion, p, if students who commute father than fifteen miles to school is more than 15%. To test this, she selects a random sample of 250 students at this college, and she finds that 49 commute farther than fifteen miles to school, is there enough evidence to support the administrator’s claim at the 0.10 level of significance? Perform a one-tailed test. Then complete the parts below. Carry you intermediate computations to three or more decimal places and round your answers as specified in the table.

A manufacturer of hand-held calculators receives large shipments of printed circuits from a supplier. It is too costly and time-consuming to inspect all incoming circuits, so when each shipment arrives, a sample is selected for inspection. Information from the sample is then used to test H0: p = 0.01 versus Ha: p > 0.01, where p is the actual proportion of defective circuits in the shipment. If the null hypothesis is not rejected, the shipment is accepted, and the circuits are used in the production of calculators. If the null hypothesis is rejected, the entire shipment is returned to the supplier because of inferior quality. (A shipment is defined to be of inferior quality if it contains more than 1% defective circuits.) In this context, define Type I and Type II errors. (Select all that apply.) a. A Type I error is obtaining convincing evidence that more than 1% of a shipment is defective when in fact (at most) 1% of the shipment is defective. b. A Type I error is not…
Past records from a local hospital stated that the proportion of full-term babies born in the hospital who weigh less than seven pounds is 43%. Suppose that we have strong reason to believe the proportion is greater than 43%, and we wish to carry out a hypothesis test. State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test. H0: H1:
When is a researcher at risk of making a Type II error? a. whenever H1 is rejected b. whenever H0 fails to be rejected c. whenever H0 is rejected d. The risk of a Type II error is independent of the decision from a hypothesis test.
A car manufacturer claims that its latest model can average 60 miles per gallon on the highway - and an auto magazine's editor wants to put that claim to the test. (a) Write the null hypothesis for this situation. (b) Write the alternate hypothesis, if the editor wants to prove that the actual miles per gallon is lower than what's being claimed. (c) Write the alternate hypothesis, if the editor wants to prove that the actual miles per gallon is simply different from what's being claimed.
In each problem show all steps of the hypothesis test using PHANTOMS. If some of the assumptions are not met, note that the results of the test may not be correct and then continue the process of the hypothesis test. The Kyoto Protocol was signed in 1997, and required countries to start reducing their carbon emissions. The protocol became enforceable in February 2005. In 2004, the mean CO2 emission was 4.87 metric tons per capita. Table 7.3.3 contains a random sample of CO2 emissions in 2010 ("CO2 emissions," 2013) from 30 countries. Is there enough evidence to show that the mean CO2 emission is lower in 2010 than in 2004? Test at the 1% level. Table #7.3.3: CO2 Emissions (in metric tons per capita) in 2010 1.36 1.42 5.93 5.36 0.06 9.11 7.32 2.86 7.93 6.72 0.78 1.80 0.20 2.27 0.28 2.44 5.86 3.46 1.46 0.14 2.62 0.79 7.48 0.86 7.84 2.87 2.45 5.85 3.45 1.45
3)If we have a sample of size 100 with sample mean breaking strength of 975 pounds from a population of rope with standard deviation 200 pounds and we wish to run a hypothesis test with this data to see if the population mean breaking strength differs from 1000 pounds, what is the significance of our data?

A paint manufacturer advertises that one gallon of its paint will cover 400 square feet of an interior wall. Some local painters suspect the average coverage is considerably less and decide to conduct an experiment to find out. Which of the following are the correct null and alternative hypotheses to be tested? A construction company has a bid on two large construction projects. The president believes that the chances of winning the first contract is 55% and the chances of winning the second contract is 30% and that winning either contract is independent of winning the other. What are the chances the company will not win either contract? Spelling mistakes in a text are either “nonword errors” or “word errors.” A nonword error produces a string of letters that is not a word, such as “the” typed as “teh.” Word errors produce the wrong word, such as “loose” typed as “lose.” Nonword errors make up 25% of all errors. A human proofreader will catch 80% of nonword errors and 50% of…
In a hypothesis test with hypotheses H0: p = 0.26 and H1: p ≠ 0.26, a random sample of size 809 produced a sample proportion of 0.2400. The test is to be made at the 5% significance level. You --------------- the null hypothesis. Question 20 options: 1) fail to reject 2) reject 3) No decision is possible 4) fail to accept
What is the null and alternative hypothesis for the following problem? Thank you
A physician wants to test two blood glucose meters to see if there is any differences in measurements. To do this, he measures the glucose in blood samples taken from several randomly selected patients with both meters. Identify the null and alternative hypotheses for a hypothesis test, where each difference is calculated by subtracting the measurement on the second meter from the measurement on the first meter. A. H0:μd=0 Ha:μd>0 B. H0:μd=0 Ha:μd≠0 C. H0:μd=0 Ha:μd<0 D. H0:μd≠0 Ha:μd=0
Given that the P-value for the hypothesis test is 0.000 when rounded to three decimal places, what do you conclude? What do the results indicate about the rule that women and children should be the first to be saved?
