I need help identifying if the two sample means are dependent or independent.

I also need help creating the null and alternative hypothesis.

The Null hypothesis is simple, Null Hypothesis (H0): 1= 2

I am having trouble with the Alternative Hypothesis, should it be > or

Alternative Hypothesis (H1): 1> 2

I need help identifying if the two sample means are dependent orindependent. I also need help creating the null and alternative hypothesis.The Null

Study #3: Psychology Some people believe that reading text printed on Light Blue Paper White Paper colored paper is easier than reading text on white (seconds taken to (seconds taken paper, For this reason, disability services locations read passage) to read passage) often provide colored filters that are clear to put over 70 65 top of books and imprinted pages. 113 100 50 40 Irvine University, a public research institution with 138 120 30,000 undergraduate students, is considering the possibility of providing colored filters for those people 77 74 in disability services who would be helped by this tool. 120 100 Irvine University randomly tested 31 students in their 100 90 learning disability program during the first week of 79 classes in Fall 2018, The students, of varying ages, 67 60 abilities, majors, and socioeconomic status were timed 73 71 as they read a passage printed in black ink printed on 67 74 white paper and then timed reading a similar passage printed with black ink on light blue-colored paper. 70 68 Students were tested on one day with a passage on 110 90 white paper and then asked to willfully return the next 95 85 day to read a similar, but different passage of the same 49 44 length and difficulty level, on light blue-colored paper, 75 69 60 58 Is there sufficient evidence to show that reading text on light blue-color paper is more effective? You are 82 75 asked to organize and analyze this data, and present 78 your results to the university with a hypothesis test on 74 whether or not there is significant improvement in 100 85 reading speed. 102 100 96 90 Please present a report to Irvine University's Disability Services directors that includes your data, results, and 64 64 related evidence from national studies. 73 73 93 94 85 75 69 65 91 92 112 100 124 105Part 3: Analysis of Data - Examination of Inferential Statistics (tables of results, and appropriate hypothesis test steps) hypothesis test. Assuming that all assumptions have been met, it is now time to analyze the data. Present a complete 1. Identify the claim. 2. State the null and alternative hypotheses, in words and in symbolic form. 3. Explain what type of test you will be performing (i.e. a test of two dependent means, a test for correlation, etc.) and why that test is appropriate to address the main question you are trying to answer. 4. Select the significance level and determine if it is a one or two-tailed test. 5. Identify the test statistic and compute the value of the test statistic and the p-value. 6. Make a decision of whether to Reject or Fail to Reject the null hypothesis. 7. Restate your decision in nontechnical terms. That means, state your conclusion in a way that anyone can understand; a final conclusion that just says "reject the null hypothesis" by itself without explanation is not helpful to those who hired you. Explain in ordinary terms what it means. Part 4: Conclusion and Recommendations (approximately 3 paragraphs) Summarize and explain your results. Provide recommendations. 1. What can you infer from the statistics? 2. What information might lead you to a different conclusion? 3. What variables are missing? 4. What additional information would be valuable to help draw a more certain conclusion? 5. What qualitative or quantitative data would you want to collect if you were hired to do a follow up study
