According to a research report, 65% of the adults in the U.S. support more restrictive gun control measures. The approval of gun control in a random sample of 278 U-Albany students is 73%. Are U-Albany students more likely to approve gun control than adults in the U.S.? Use α=0.05.   Find the p-value (round to 4 decimals or put 0 if < 0.0001)

claim that the mean IQ score of people With low blood lead levels is higher than the mean IQ score of people with high blood lead levels.

In a data set with 25 scores, if the value 16 occurs 12 times, what is its relative frequency?

A survey organization, as part of the United States Census Bureau, conducts a yearly census similar to the one taken every ten years, but with a smaller percentage of participants. One of these surveys estimates with 90% confidence that the mean household income in the U.S. falls between $69,709 and $69,917. Find the point estimate for mean U.S. household income. (Enter your answer as a whole number.) x = Find the error bound for mean U.S. household income. (Enter your answer as a whole number.) EBM =

A psychology student conducted a study on using a chief executive​ officer's facial structure to predict a​ firm's financial performance. The facial​ width-to-height ratio​ (WHR) for each in a sample of 55 CEOs at publicly traded firms was determined. The sample resulted in x=1.74 and s=2.02. The student wants to predict the financial performance of a firm based on the value of the true mean facial WHR of CEOs. The student wants to use the value of μ=2.3. Do you recommend he use this​ value? Conduct a test of hypothesis for μ to help you answer the question. Specify all the elements of the​ test, including H0​, Ha​, test​ statistic, p-value, and your conclusion. Test at α=0.10.   Find the​ p-value.   ​p-value=enter your response here ​(

A time study analyst observed a repetitive work cycle performed by a worker. During the observation, the analyst made a record of the work elements. She also made a note of the worker's performance and rated it as 95%. Back in the office, the analyst listed the basic motion elements for the task and the sum of the normal times for the basic motion elements was 1.38 minutes. The company uses a PFD allowance factor of 15%. What is the standard time for the task? Tstd 1.225 minutes/unit Tstd 1.587 minutes/unit Tstd 0.625 minutes/unit Tstd 1.959 minutes/unit =

How would I identify the p-value?
