Conduct a full hypothesis testing on the following problem and then choose among the options what bestfits the items being asked:To test a claim that eating fish makes one smarter, a random sample of 12 persons take a fish oilsupplement for one year and then are given an IQ test. Here are the results:116 111 101120 9994 10611510791 101 92Is there sufficient evidence to support the claim if the standard IQ on record is 100? Use 5%significance level.Note: Round off the mean and SD in this given to 1 decimal place only, and the test statistic value to3 decimal places. If two-tailed test is to be applied, the given critical values as options are consideredthe absolute values.Identify the following:• Statistical Test: Select• Critical Value: Select]• Test Statistic: Select]• Conclusion: Select ]

Create a research hypothesis that would be answered using either a z- or a t- test. I was thinking of doing a study on college students and the amount of articles they read in one year. Include the following: Introduction: Brief description of the study including the purpose and importance of the research question being asked. What is the null hypothesis? What is the research hypothesis? Participants/Sampling Method: Describe your sampling method. What is your sample size? Who is your population of interest? How representative is the sample of the population under study? Data Analysis: Describe the statistical analysis. What is your variable? What is its level of measurement? What is your alpha level? Results & Discussion: Did you reject the null hypothesis? What information did you use to lead you to your conclusion? Was your p value greater than or less than your alpha? NOTE: You can just make up numbers, but include your made-up p value
