Pleаse nоte thаt this questiоn cоnsists of five pаrts. You may use MINITAB to find a final answer. However you MUST show all the mathematical work to get to the final answer. Just giving the answer without adequate work/explanation may result in zero for the question. The probability is 0.32 that the gestation period of a woman will exceed nine months. In randomly chosen six human births, let X = Number of births in which gestation period exceeds nine months from these six births. 1. What is the distribution of X? Clearly state the parameters of the distribution. 2. Write down the probability mass function, for the distribution of X. That is, write the probability mass function specific for the random variable of interest in this problem, not just the general formula. 3. What is the probability that none in the sampled 6 human births gestation period exceeds nine months? 4. What is the probability that the gestation period exceeds nine months in at least one in the sampled 6 human births? 5. Would it be unusual if the gestation period exceeds nine months in all sampled 6 human births? Show any calculation relevant to your answer.

Pleаse nоte thаt this questiоn cоnsists of six pаrts. You need to show all mathematical calculations to get the final answer. Just giving the answer without showing work may result in zero for the question. A research group is interested in determining whether teenagers obtain their drivers licenses at approximately the same average age across the country. Data on the age at which teenagers obtained their drivers license are randomly collected from teenagers in each of five different regions of the country. Research group who conducts the study have decided to use One-way ANOVA to compare the mean age at which teenagers obtained their drivers license for the five regions tested. They need help from a statistician to interpret the results. Use provided partial output to answer the following questions. Write down the null and alternative hypotheses for testing whether or not the mean age at which teenagers obtained their drivers license are the same for the five regions tested. Use properly defined parameters when you set up null and alternative hypotheses. Compute the degrees of freedom missing in the ANOVA output (i.e. error degrees of freedom) Compute the sum of squares missing in the table (i.e.: Sum of square treatment) Compute the F-value missing in the ANOVA output. At a 5% significant level is there sufficient evidence to claim that the true mean age at which teenagers obtained their drivers license is different for at least one of the regions. Explain your answer. The output for Tukey pairwise comparisons is given below. Based on the output Are the mean age at which teenagers obtained their drivers license for the regions of East and Norteast significantly different? Explain your answer. Which region seems to have the highest mean age at which teenagers obtained their drivers license?

This аssessment аligns with Student Leаrning Objective H, I, J, L. Please refer tо yоur cоurse syllabus for more information.Quiz Overview & InformationHow many questions? This quiz will consist of 12 questions.What is the time limit? Students will have 30 minutes to complete. You will notice a timer in the corner of the screen during the quiz. Blackboard will automatically shut off after the allowed time; any unanswered questions will be counted wrong.How is it graded? Blackboard will automatically grade your quiz after you save and submit your answers. You will not be able to see what you missed automatically. After the deadline, results will be viewable.What Else Do I Need to Know Before I Start?Try to complete the test in one sitting. This means you may not log off and finish at a later time after you start. This also means you may not navigate away from the testing window, doing so will result in the quiz auto-submitting. Therefore, before you start the quiz, ensure you have closed all pop-up windows and security settings. Also ensure you have a stable internet connection. Do not use a mobile device to complete a quiz. Mobile signals are often unstable, therefore it is best again to use a computer that is hardwired into your internet connection if possible.What if there is a technical problem? Should you be ‘knocked offline’ or ‘kicked out’ during the quiz or have some other technical difficulty, send me an email immediately explaining what happened plus tell me what steps you have taken or will take to prevent this from happening again. If you need technical help with Blackboard, SJC Blackboard Technical Support can be reached at 281-542-2084.How do I complete the test?
