- Meth Barie's ice cream shop wants to decide whether to introduce a new ice cream flavor. They randomly selected 15 customers at their downtown Denton location to rate this new flavor. The rating is on a scale of 1 to 5, with 1 being 'not interested' and 5 being 'strongly interested'. Meth Barie's will approve the new flavor if the true mean rating is over 4.0. What is the rejection region for testing at the 0.1 level of significance?(The output processed data is in the picture below) A company has four branch offices. At each branch office, the research was carried out using a random sample, then the data was processed using ANOVA with the following results: Based on the results of data processing, answer the following questions: a. What is the number of samples (N) used in the study?b. State the value for F-countc. Using the significance level or the Alpha (α) value 4%, test the hypotheses in the study and provide the conclusion.d. How do you think the conclusions of the research are?Find the critical value(s) and rejection region(s) for the indicated t-test, level of significance α, and sample size n. Two-tailed test, α = 0.10, n=13 The critical value(s) is/are?
