The average farm size in the United Statesis 444 acres. A random sample of 50farms in New York indicated a mean sizeof 460 acres, and the population standarddeviation is 54 acres. At a0. 05,can it be concluded that the average farmin New York differs from the nationalmean?Please show all work in performing yourhypothesis test below. Be sure to includenull and alternative hypotheses, criticalvalue, test value and your conclusion.

We have given that Population mean = 460 Sample mean = 444 Sample size = 50 Population standard…

Historically, the percentage of U.S. residents who support stricter gun control laws has been 55%. A recent Gallup Poll of 2500 people showed 1723 in favor of stricter gun control laws . Assume the poll was given to a random sample of people. QUESTION Test the claim that the proportion of those favoring stricter gun control has changed from 0.55. Perform a hypothesis test, using a significance level of 0.01. . What is the Z crit? +/- 1.96 +/- 1.645 +/- 2.58 +/- 2.326
One way to check on how representative a survey is of the population from which it was drawn is to compare various characteristics of the sample with the population characteristics. A typical variable used for this purpose is age. The GSS 2018 found a mean age of 48.69 and a standard deviation of 17.99 for its sample of 1,495 American adults. Assume that we know from census data that the mean age of all American adults is 37.80. What is the research and the null hypotheses for a two-tailed test of means, calculate the t statistic and test the null hypothesis at the .001 significance level, and what is the decision about the null hypothesis?
New York State claims that the average cost for gasoline is less than $2.60 per gallon.You think this information is incorrect, so you travel to 41 different gas stations and findthat the mean cost of gas is $2.57 per gallon. Assume the population standard deviationis $0.25 per gallon. Is there enough evidence to support the claim for ? = 0.01? Be sureto identify the null and alternative hypotheses.
A data set includes data from 500 random tornadoes. The display from technology available below results from using the tornado lengths (miles) to test the claim that the mean tornado length is greater than 2.4 miles. Use a 0.05 significance level. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. i Click the icon to view the display from technology. Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. Ho: μ=2.4 miles O B. Ho: μ=2.4 miles H₁: μ#2.4 miles H₁: μ 2.4 miles Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.)
