atSuppose a professor is interested in seeing whether or not they hold their student's attention longer than averageUniversity. Assuming the average number of times that a student checks their phone within a 50minute class is 4.2, determine whether or not the data the professor has collected supports their hypothesis.Below are counts of number of times the professor has seen individual students in their class check their phoneswithin one class.2, 2, 1, 1, 6, 5, 5, 0, 3, 3, 1, 1, 1, 1, 31. Using the data provided, determine the null and alternative hypotheses. Then determine how many tails thisresearch question has2. Using the data provided, use what you have learned in Excel to calculate the standard deviation for thesample and the SEMs for the sample3. Use the calculated SEMs and other values from question 2, calculate your obtained t-statistic for this researchquestion4. Using Appendix B in your text, the degrees of freedom for this research question, and the number of tailsyour hypothesis has to determine the t-critical value5. Based on your calculated t-statistic and t-critical value, engage in hypothesis testing. What is your decisionregarding the research question

The observed number of times, the sampled individual students were seen checking their phones is: 2,…

People often say “Distance makes the heart fonder.” Interestingly, due to pandemic related lockdowns, some persons have been implicitly or explicitly indicating that it is indeed true as they have been struggling with their relationships due to lack of time apart from their partner. A researcher who is interested in such an issue decided to collect data on the level of rage/edginess that exist among a few couples due to lockdowns. Participants were asked to rank the level of hostility they think they have been exerting towards their partner due to having to spend more time than they usually do with them. The resulting data is presented on page two (2). 2 *14 is the highest level of hostility. Level of hostility Number of partners 0-1 4 2-3 11 4-5 8 6-7 20 8-9 25 10-11 12 12-13 12 13-14 4 a.

The blue catfish (Ictalurus Furcatus) is the largest species of North American catfish. The current world record stands at 143 pounds, which was caught in the John H. Kerr Reservoir (Bugg's Island Lake) located in Virginia. According to American Expedition, the average weight of a blue catfish is between 20 to 40 pounds. Given that the largest blue catfish ever caught was at the John H. Kerr Reservoir, you believe that the mean weight of the fish in this reservoir is greater than 40 pounds. Use the data below, which represents the summary statistics for 42 blue catfish caught at this reservoir, and a 0.05 significance level to test the claim that the mean weight of the fish in the John H. Kerr Reservoir is greater than 40 pounds. n=42; ¯x=40.63 pounds; s=3.49 pounds a) Identify the null and alternative hypotheses?H0: H1: c) Identify the appropriate significance level.d) Calculate your test statistic.
