It has recently been claimed that 25% of adults consider spring to be their favorite season of the year. A researcher is skeptical of this claim and believes this percentage is too low. She surveys a random of 1,000 adults and finds that 390 of these adults consider spring to be their favorite season of the year. As she prepares to conduct a hypothesis test, the researcher writes out her alternative hypothesis as “p < 0.25.” What is wrong with this? The alternative hypothesis should be “p > 0.39.” The alternative hypothesis should be “p < 0.39.” The alternative hypothesis should be “p > 0.25.” The alternative hypothesis should be “p = 0.25.” Nothing is wrong with the given alternative hypothesis.
Perform a hypothesis test at a 5% level of significance to see if the proportion of white individuals who are fatally shot by police is less than the total proportion of white individuals in the United States, which is approximately 60.1% according to the U.S. census bureau.

Please answer A B C(a) What conditions should you check first before you conduct the hypothesis test?(b) Write the null and alternative hypotheses.(c) What type of test are you doing: right-tailed, left-tailed or two-tailed?(d) What formula should be used for the test statistic?(e) What number is the test statistic equal to?(f) Sketch a graph of the p-value(g) What p-value do you obtain? Round to the ten-thousandths.(h) Do you reject the null hypothesis or fail to reject the null hypothesis? Explain.(i) Please write a conclusion sentence, in the context of the problem, that explains to a lay person the result of the hypothesistest.
Let’s say your grandfather is 72 years old and your question is “Are my classmates’ grandfathers, on average, older than mine is”? What would be the null and alternative hypotheses in this scenario?

Ha : The population average age is less than 72. H0 : The population average age is equal to 72. Ha : The population average age is less than 72. H0 : The population average age is equal to 72. Ha : The population average age is greater than 72.
Which hypothesis test would be appropriate to determine whether the new variety of orange has a significantly higher content of vitamin C than the variety that is currently the top seller? Do NOT perform a hypothesis test – simply tell me which test should be used, why you chose this test, and give the formula for the test statistic.
Let’s assume the average income for all majors in the School of Engineering is $80,000. However, the chair of the Computer Science department thinks their students earn more than that. Please choose the appropriate null and alternative hypotheses if the chair wanted to test this belief. a. H0: u <=80,000 Ha: u > 80,000 b. H0: u= 80000 Ha: u not= 80000 c. H0: u >80000 Ha: u < 80000 d. H0: u >80000 Ha: < 80000 e. None of the above.
You may need to use the appropriate appendix table or technology to answer this question. In 2012, seventy percent of Canadian households had an internet connection. A sample of 370 households taken in 2013 showed that 76% of them had an internet connection. We are interested in determining whether or not there has been a significant increase in the percentage of the Canadian households that have internet connections. (a) State the null and alternative hypotheses to be tested. (Enter != for as needed. Let p be the proportion of all Canadian households with internet connections.) Ho: на: (b) Compute the test statistic. (Round your answer to two decimal places.) (c) The null hypothesis is to be tested at the 5% level of significance. Determine the critical value(s) for this test. (Round your answer(s) to two decimal places. If the test is one-tailed, enter NONE for the unused tail.) test statistic (d) What do you conclude? Do not reject Ho. We can conclude that there has been a…
Let’s say Mrs. Smith was 72 inches tall, and her question was “Are my students, on average, shorter than I am?”. What would be the null and alternative hypotheses in this scenario? A.

How do you write a null hypothesis and an alternative hypothesis in words? This is the question: The survey question: On the average day, about how many hours do you personally watch television? Suppose that your reading of professional research on the topic leads to the hypothesis that, on average, adults in the US watch three hours of TV each day. I planned to use a two-sided alternative hypothesis. In symbol, my null hypothesis would be H0 : equal 3 and my alternative hypothesis would be Ha not equal 3
