A professor asks her students to select which day they would prefer to have their exam: Mon, Wed, or Fri. Do students equally prefer all three options? Which test is most appropriate to conduct? One-way ANOVA Independent t-test Dependent t-test z-test Chi-sqaure

Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Ho: p = 0.2 versus H,: p> 0.2 n= 125; x= 40; a = 0.05 Click here to view page 1 of the table. Click here to view page 2 of the table. Calculate the test statistic, zg. Zo = (Round to two decimal places as needed.)

Scenario: 200 people were asked, “Who is your favorite superhero?” Below are the data.  Test the null hypothesis that the population frequencies for each category are equal.  α= .05. Iron Man Black Panther Wonder Woman Spiderman fo = 40 fo = 60 fo =55 fo = 45 fe = fe = fe = fe =   What is the correct result based on the data?

Given H:u= 25, Hu=25, and P = 0.028. Do you reject or fail to reject H, at the 0.01 level of significance? do O fail to reject H O reject H O not sufficient information to decide

Styles Font Paragraph Hypothesis Testing for College Tuition Cost D) Calculate the mean and standard deviation of your data set. You may use technology such as Google Sheets, Excel, or a TI-83/TI-84. Round to the nearest hundredth. In this assignment, you will be using inferential statistics to determine if a claim about college tuition cost is accurate. Standard Deviation According to the College Boarď's website, the average tuition cost per year for a public four- year college (in-state cost) is $10,230. Mean & A) Assume that you disagree with the claim. Do you think the average tuition cost is higher? Or lower? E) Using a significance level a = 0.05, find the critical value using the following steps. 1. What are the degrees of freedom? B) Using your answer in part A, write a set of hypotheses (null hypothesis and alternative hypothesis) to represent that claim and its complement. Replace the ?s below with the appropriate inequality signs (,2). Highlight the hypothesis that…
