Consider the following data. 0,-11,-11,- 11, -9, 0,0 Step 1 of 3: Determine the mean of the given data.

The given data set is: 9 5 23 26 11 11 Find the median. Find the mean. Round to one decimal place as needed. Find the mode. If the mode does not exist, please enter DNE. If there are multiple modes, please separate them by space and in increasing orde

Derrick is preparing to submit his taxes.  Over the year, he kept track of certain deductions he is able to claim  (all rounded to the nearest dollar).  These values are given below.    65,144,97,144,103,98,101,127,58,151 He wants to create a histogram of the data using 4 classes. What values of Xscl, Xmin, and Xmax should he use?

The boxplot below displays the average number of jumbo marshmallows consumed in eating contests across a particular state. The higher outlier is from a professional, heavyweight contest, and the lower outliers are from children's eating contests.What effect will removing all outliers have on the mean and median of the data set?  Neither the mean nor the median will change.  The median will change and the mean will increase.  The median will change and the mean will decrease.  or The mean will remain unchanged and the median will increase.

For the data set 8 14 6 10 9 the median is

Jocelyn believes that the amount of sleep she tends to get on weekends differs from the amount of sleep she tends to get during the school week. To investigate this claim, she randomly selects 10 weekend days and 10 school days. She consults her smart watch to determine the number of hours she slept for each of the selected days. Here are the data. School week: 7, 7.5, 8, 6.5, 8, 7.5, 7, 6.5, 7, 8Weekend: 9.5, 9.5, 8.25, 8.5, 7.5, 10.25, 8, 7, 9.5, 10 Jocelyn would like to determine if these data provide convincing evidence that the true mean amount of sleep she gets on the weekend differs from the true mean amount of sleep she gets during the school week. She tests H0: μS – μW = 0, Ha: μS – μW ≠ 0, where μW = the true mean amount of sleep Jocelyn gets on the weekend and μS = the true mean amount of sleep she gets during the school week. The conditions for inference are met. What are the values of the test statistic and P-value for a t-test about a difference in means? Find the…
