I am going to do an experiment where I roll a die a large number of times. I am interested in whether the die lands with 2 or 3 spots showing. The '2 or 3 spots' is the O S O o 0 Event 0 Sample space I rated 20 images all with Blue backgrounds. You rated 40 images all with red backgrounds. We were exposed to different O Treatments O Continuous variables O Subjects O Infinite sample spacesA. The population has a mean of 196 and a standard deviation of 49. We sample 36 people from this population and repeat this process 25 times. B. The population has a mean of 169 and a standard deviation of 25. We sample 81 people from this population and repeat this process 49 times. Which of the two scenarios will have a wider sampling distribution? O It's a tie O A O BA set of test scores is normally distributed with a mean of 400 and a standard deviation of 100 What score is necessary to reach the 80th percentile? Select the closest answer. 0 434.2 0 84.1% 0 84.16 080
