2. Suppose you were taking a statistics course where the final grade breakdown ended up being the following: 8 A's, 6 B's, 5 C's, 2 D's, 1 F. Create a bar graph of this data using either your calculator or iPad and upload an image of that bar graph on this discussion. Please visit the uploading images page on Canvas for instructions on how you can upload images for this discussion.

In a study, researchers wanted to measure the effect of alcohol on the hippocampal region, the portion of the brain responsible for long-term memory storage, in adolescents. The researchers randomly selected 23 adolescents with alcohol use disorders to determine whether the hippocampal volumes in the alcoholic adolescents were less than the normal volume of 9.02 cm. An analysis of the sample data revealed that the hippocampal volume is approximately normal with no outliers and x 8.18 cm and s=0.8 cm. Conduct the appropriate test at the a= 0.01 level of significance. State the null and alternative hypotheses. Ho: H H1: (Type integers or decimals. Do not round.) Identify the t-statistic. to = (Round to two decimal places as needed.) !! Identify the P-value. P-value = (Round to three decimal places as needed.) Make a conclusion regarding the hypothesis. the null hypothesis. There sufficient evidence to claim that the mean hippocampal volume is cm³ Statcrunch Next 8:01 SAMSUNG esc @ %23 $…

There are five numbers in a data set. They are 3, 1, 16, 20 and x, where x is one of the largest two number of the five. What value does x need to be so that the median of the five numbers equals the mean of the five numbers?

Please select some data that interests you from a source of your choice.   One set of data works the best, and if you pick a data set with at least 20 pieces of data, you will be able to use the same set of numbers for the Week 8 Discussion forum. Find the mean, median, mode, range, 5-number summary, and either a histogram or a box plot (you do not need to do both). Discuss your findings in your posting and attach your Excel worksheet for others to view.

Continue monitoring the process. A second ten days of data have been collected, see table labeled “2nd 10 Days of Monitoring Reservation Processing Time” in the Data File. Develop Xbar and R charts for the 2nd 10 days of monitoring. Plot the data for the 2nd 10 days on the Xbar and R charts. Is the reservation process for the 2nd 10 days of monitoring in control?  If the control chart indicates an out-of-control process, note which days, the pattern, and whether it is the Xbar or R chart.   Based on the X-bar and R Charts that you developed for the 2nd 10 days of data, is the process in control?   Group of answer choices No. The X-bar and R Charts are both out of control. No. The X-bar Chart is in control, but the R Chart is out of control. No. The R Chart is in control, but the X-bar Chart is out of control. Yes. The X-bar and R Charts are both in control.
