W7D: Discussion A+ Instructor Example: We were introduced to hypothesis testing. We will continue our study this week. Hypothesis testing is very similar to a criminal trial, where a jury must use evidence to decide which of 2 possibilities is the truth: innocence (H0) or guilt (HA). In your initial post, address the following prompts: Describe a hypothesis test study that would help your work or conclusions in some way. Describe what variable would be tested and what would be your guess of the value of that variable. Discuss how the result, if the null was rejected or not, might change your conclusions or actions in some way. Teas made with ingredients such as chamomile, spearmint, and lemongrass are becoming more and more popular as a relaxing bedtime drink. Perhaps you'd like to test the powers of Sleepytime tea. Your hypothesis might go something like this: • Null hypothesis - Sleepytime tea has no effect on people's ability to fall asleep. Alternative hypothesis - Sleepytime tea helps people to fall asleep. Significance level - The significance level is 0.20 (allowing for a better shot at proving your alternative hypothesis). P-value - The p-value is calculated as 0.05. Conclusion - After providing one group with Sleepytime tea and the other with a placebo drink, you gauge the difference between the two based on self-reported levels of anxiety. Based on your calculations, the difference between the two groups is statistically significant with a p-value of 0.05, well below the defined alpha of 0.20. You conclude that your study supports the alternative hypothesis that Sleepytime tea can help people fall asleep. In order to engage in an active discussion environment, submit your initial discussion post by Wednesday. For detailed grading criteria, refer to the Discussion Rubric.

Please do not give solution in image format thanku Do our children spend enough time enjoying the outdoors and playing with friends, or are they spending more time glued to the television, computer, and their cell phones? A random sample of 250 youth between the ages of 8 and 18 showed that 160 of them had a TV in their bedroom and that 90 had a video game console in their bedroom. Estimate the proportion of all 8- to 18-year-olds who have a TV in their bedroom and calculate the 95% margin of error for your estimate. (Round your margin of error to three decimal places.)

Round using 3 decimal places and enter percentages as numbers between 0 and 1 (e.g., if result is 53.478% enter 0.535) Use the variable metacritic (the metacritic critic score) from data-frame fandango (need to obtain from package fivethrityeight) b) Using the actual data, what is the percentage of metacritic critic scores that are greater than 70 and less than or equal to 95?
