The following table contains the number of successes and failures for three categories of a variable. Test whether the proportions are equal for each category at the α = 0.01 level of significance. Failures Successes Category 1 Category 2 80 58 73 65 State the hypotheses. Choose the correct answer below. Category 3 D 45 41 A. Ho: P₁ P2 = P3 H₁: At least one of the proportions is different from the others. B. Ho: ₁=E₁ and μ₂ = ₂ and μ3 = E3 H₁: At least one mean is different from what is expected. C. Ho: The categories of the variable and success and failure are dependent. H₁: The categories of the variable and success and failure are independent. What is the P-value? D. Ho: The categories of the variable and success and failure are independent. H₁: The categories of the variable and success and failure are dependent. (Round to three decimal places as needed.)

After you have clicked the tab for your selected topic and read the problem, answer the questions below. (a) Use SALT to summarize the data. Enter the sample size, number of success, and sample proportion, p for the data, rounded to three decimal places. Sample size Number Successes 4129 1938 0.4691 (b) Write the hypotheses to investigate the research question about the proportion, p, of successes. (Enter != for # as needed.) Ho: 0.4691 H: 0.05 (c) We need to verify the assumptions for using a z-test for a single proportion to analyze this dataset. the population of interest or the sample is The first assumption states the sample is a random sample selected in a way that should result in a representative sample. Based on what you know about how this sample was collected, the sample is a random sample from the populations of interest. The second assumption requires the sample to be large enough to be reasonably sure that the sampling distribution will be at least approximately normal.…

Hi could you answer whats blank?

uppose you reject the null hypothesis H0: μ = 101. It turns out the population mean is actually equal to 101.   You have made a Group of answer choices Type I and Type II errors the correct decision Type II error Type I error

p and z values please

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 =   Chi Square test statistic = ______ Group of answer choices
