Please help. State the hypothesis and identify the critical and z-values. ### Home Runs Analysis**Objective:** We aim to determine if there is a significant difference in the mean number of home runs hit by players from the National League and the American League. To do this, we will use the P-value method with an alpha level (\(\alpha\)) of 0.10, and perform the analysis using a TI-83 Plus/TI-84 Plus calculator.#### Data Samples:- **National League:** 18, 4, 2, 9, 6, 5- **American League:** 18, 12, 25, 4, 24, 12You can also export the data to Excel for further analysis by clicking the "Send data to Excel" button.#### Instructions:Use \(\mu_1\) for the mean number of home runs from the National League. Assume the variables are normally distributed and the variances are unequal.### Hypothesis Testing:**Step 1: State the Hypotheses**- **Null Hypothesis (\(H_0\)):** There is no difference in the mean number of home runs between the National League and the American League.- **Alternative Hypothesis (\(H_1\)):** There is a difference in the mean number of home runs between the National League and the American League.**Step 2: Identify the Correct Test**- **Test Type:** Two-sample t-test for unequal variances (Welch’s t-test).### Interactive Component:1. **Question:** State the hypotheses and identify the claim with the correct hypothesis. - **\(H_0\):** (Choose one) - **\(H_1\):** (Choose one) The hypothesis test is a (Choose one) test.2. **Answer Submission:** Complete the four parts of the hypothesis test to interpret the results.**Part 0 / 4**: You will start with a score of 0 and progress as you correctly identify and input the required information. Each part will guide you through the process systematically, ensuring a thorough understanding of the hypothesis testing involved.This interactive approach helps you practice and understand the application of hypothesis testing in real-world scenarios, specifically in comparing means from two different samples with potentially unequal variances.

From the given information we conduct Hypothesis test.

A researcher selects a sample and administers a treatment for anxiety to the individuals in the sample. If the sample is used for a hypothesis test, what does the alternative hypothesis (H1) put forth about the treatment? Group of answer choices The treatment has no effect on anxiety. The treatment adds a constant to each anxiety score. The treatment multiplies each anxiety score by a constant. The treatment has an effect on anxiety.
The ACME golf ball company believes they have created a golf ball that will travel 25 yards further than the top brand--Brand X. To test this, they recruited 40 professional golfers and had each golfer drive the ACME ball and measure the distance, then drive Brand X's ball and measure the distance. Which hypothesis test is most appropriate to use in this scenario? ● Two-sample t-test Paired t-test Two proportions test Multiple linear regression
Find the P-value of z-score (3.55) if doing a two-tail hypothesis test.
A research report includes the statement, “ z = 1.18, p > .05.” What happened in the hypothesis test? The obtained sample mean was very likely if the null hypothesis is true, so H0 was rejected. The obtained sample mean was very unlikely if the null hypothesis is true, and the test failed to reject H0. The obtained sample mean was very unlikely if the null hypothesis is true, so H0 was rejected. The obtained sample mean was very likely if the null hypothesis is true, and the test failed to reject H0.
Read through this scenario and look at the data that was collected. State the null and all possible research hypotheses. Review the results below (I used SPSS) and answer the questions that follow. Scenario: A researcher wants to see if gender and / or income affects the total amount of help given to a stranger who is sitting on the side of a busy road with a sign asking for help. The independent variables are gender, income, and the interaction of gender and income. The dependent variable is total help. He wants to know if one or both factors – or the interaction of the two - affects the total amount of help offered. Because he is analyzing two independent variables (gender and income), he used a factorial ANOVA. His results show the main effect of each of the independent variables on the dependent variable (total help) and the interaction effect. The researcher is using a 95% confidence interval which means that he wants to be at least 95% sure that his independent variables…
