PLEASE HELP WITH THE PROBLEM BELOW Let pm and pf be the respective proportions of male and female white-crowned sparrows that return to their hatching site. We observed that 124 out of 894 males and 70 out of 700 females returned. Does your result agree that there is no difference between the proportions of male and female white-crowned sparrows that return to their hatching site with α = 0.05? Formulate the hypotheses Finish the hypothesis testing and draw your conclusion (use p-value to test the hypotheses)
Evolution and Scientists. A professor claims that more than 83% of all scientists believe in evolution. In a 2014 Pew Research survey of a representative sample of 162 scientists connected to the American Association for the Advancement of Science (AAAS), 146 of these scientists say they believe in evolution. Perform a hypothesis test of the professor's claim using these data.(a) Select the correct null and alternative hypotheses. Ho: p = 0.83Ha: p ≠ 0.83 Ho: p = 0.9Ha: p ≠ 0.9 Ho: p = 0.83Ha: p > 0.83 Ho: p = 0.9Ha: p > 0.9 Ho: p = 0.83Ha: p < 0.83 Ho: p = 0.9Ha: p < 0.9 (b) Find the p-value (round to 4 decimals). (c) Decide whether or not to reject the null hypothesis when α=0.05α=0.05. Fail to reject null hypothesis Reject null hypothesis (d) You should decide that ... there is not enough evidence at α=0.05α=0.05 that more than 83% of scientists believe in evolution. there is enough evidence at α=0.05α=0.05 that more than 83% of scientists believe in evolution.

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? Group of answer choices H0 : The population average age is less than 72. Ha : The population average age is greater than or equal to 72. The population average age is greater than 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 less than 72. H0 : The population average age is equal to 72. Ha : The population average age is greater than 72.

Gender of Interviewer Man Woman Women who agree 578 314 Women who disagree 322 86 Identify the null and alternative hypotheses. Choose the correct answer below. A. H0: The response of the subject and the gender of the subject are independent. H1: The response of the subject and the gender of the subject are dependent. B. H0: The proportions of agree/disagree responses are different for the subjects interviewed by men and the subjects interviewed by women. H1: The proportions are the same. C. H0: The proportions of agree/disagree responses are the same for the subjects interviewed by men and the subjects interviewed by women. H1: The proportions are different. Compute the test statistic. Find the critical value(s). What is the conclusion based on the hypothesis test? Fail to reject/ Reject H0. There is/is not sufficient evidence to warrant rejection of the claim that the…
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.
A researcher wanted to determine if carpeted rooms contain more bacteria than uncarpeted rooms. The table shows the results for the number of bacteria per cubic foot for both types of rooms. Full data set O Carpeted Uncarpeted 9.4 9.1 16 10.8 6.4 10.8 14.8 8.8 11.5 11.6 13.7 9.4 10.7 12.4 13.4 7.8 Determine whether carpeted rooms have more bacteria than uncarpeted rooms at the a = 0.05 level of significance. Normal probability plots indicate that the data are approximately normal and boxplots indicate that there are no outliers. State the null and alternative hypotheses. Let population 1 be carpeted rooms and population 2 be uncarpeted rooms. OA Ho P1 H2 B. Ho H1 F2 OC Ho H= H2
11. The null and alternative hypotheses For each pair of hypotheses that follows, decide whether H₀ and H₁ are set up correctly as the null and alternative hypotheses for a hypothesis test. If so, select “Valid” from the drop down menu. If not, select “Invalid”. 1 H₀: μ = 76 2 H₀: M = 234 H₁: μ ≠ 76 H₁: M ≠ 234 Invalid 3 H₀: μ = 16 4 H₀: µ = 112 H₁: μ ≠ 16 H₁: µ ≠ 111 You evaluate the by assuming that it is true and testing the reasonableness of this assumption by calculating the probability of getting the results if chance alone is operating.
