please help me with stats:(( null hypothesis and alternative hypothesis, please dont cancel or close this if i still havent got answer yet :(((

KNOWLEDGE A. Directions: Express the null hypothesis H. and the alternative hypothesis Ha in notation form and sialemeni fom in the following scenarios. Write your answer on the space provided. (6 points) Example: Claim: The average monthly income of Filipino families who belong to low-income bracket is P8,000.00. Ho: The average monthly income of Filipino families who belong to low-income bracket is P8,000.00 (N= 8,000). Ha: The average monthly income of Filipino families who belong to a low-income bracket is not equal to P8,000.00 (M# 8,000). 1. The researcher claims that the average number commuters per day in Trece Martires City is less than 589 Ho: Ha: 2. The average monthly income of Senior High School teachers in private school is greater than P9,000. Ho : Ha: 3. The manager of Dzaimitan Clothing & Apparel claims that the average number of customers per day is 190. A researcher conducted her own survey. Her survey resulted in a mean of 200 Using the 0.05 significance level, can it be concluded that the mean number of customers is different from 190? Ho: Ha B. Directions: Find the Critical value of the following. (1 point each) 1. One-tailed test, s = 25; a = 0.01; n = 28 2. One tailed test, o = 96; a = 0.05; n = 35 3. Two-tailed test, s = 11; a = 0.10; n = 20 4. Two-tailed test, 62 = 64; a = 0.05; n = 29Directions: State the null and alternative hypothesis, compute the test statistics, determine the critical value and the rejection region, and draw a conclusion of the following problems. You will be graded according to the following. Null and alternative hypothesis ( 1 point) normal curve and decision ( 1 point) Critical value (1 point) - Conclusion (1 point) Test value (1point) 1. The Department of Labor and Employment released an article claiming that the unemployment rate in the Philippines as of January 2022 is 6.5%. Mayor Gemma Lubigan, wondered if this held true in Trece Martires City. They took a sample of 300 and 50 of them were unemployed. At 0.05 level of significance, can it be concluded that the unemployment rate in Trece Martires City is different from 6.5%? A business owner earned an average of P33,056.25 a month. Suppose you recently selected a random sample of 25 business owners. You determined how much each of them earns each month and your computation of their earnings resulted to an average of P30,000.00, with a sample standard deviation of P195.00. Using a 0.01 level of significance, can it be concluded that the average monthly earnings of business owners exceed P33,056.25? Assume normality in the population. 3. It is claimed that the average grades of working students in Cavite State University is 1.75. A researcher selected a random sample of 45 working students. The computation of their grades resulted to an average of 1.5 with a standard deviation of 0.25. Does this mean that the average grade of working students is different from 1.75? Use 0.10 level of significance and assume normality in the population.C. Analyze the given scenario below and write all necessary information. Scatter plot are important in statistics and research because they identify the relationship between changes in two different sets of variables. As Grade 11 student with research and statistics subject, you've been assigned to conduct a study regarding the effects of social media to the students' academic performances. The data are given below: Let x- number of hours they spent in a day in browsing their social media. y - average grades x > 96 a. Construct a scatter plot that shows correlation of two variables of bivariate data. (4 points) b. Identify the dependent and independent variable (1 point) PROCESS: Use the given data in Test C to answer the questions bellow. You will be graded according to the rubric below. CRITERION Gives a very clear Gives a clear The Fails to give a clear CONTENT answer/explanation answer/explanation answer/explanation| answer/explanation and shows very and shows neatness is partly clear, and but shows effort. neat work. of work . there are erasures.

Based on your answer in Test III (KNOWLEDGE), explain the given data, type of correlation, and scatter graph formed. Can we conclude that most students have low grades because they spend most of their time in social media? Explain your answer in 3-5 sentences. 2. Give real life examples that shows positive correlation, negative correlation, and no correlation. Explain how does each examples represents correlation
