1.I need a statistics test done, it is on hypothesis testing, and confidence interval. This is a 2 HOUR TIMED
R TIMED TEST, with 9 questions. I know what types of questions will be on the test, but I CANNOT INCLUDE THEM UNTIL WE ARE READY TO BEGIN THE TIMER. Please see my attached images, the first one on confidence intervals makes up questions 1-7, the second is a variation of these initial confidence interval questions, and the last picture shows the format of the last 2 questions on hypothesis testing. This gives you plenty of time and the questions are rather straight forward. I NEED SOMEONE ABLE TO BEGIN NOW. THE FINAL DEADLINE IS 11PM PST Thanks
