Determine if there is an outlier in the given data. If yes, please state the value(s) that are considered outliers. 16, 43, 55, 6, 39, 30, 48, 19, 43, 14, 8, 28, 27, 44 If more than one outlier exists, enter the values in the box, separating the answers with a comma. Selecting an option will enable input for any required text boxes. If the selected option does not have any associated text boxes, then no further input is required. No outliers O Outliers exist

Consider a sample with data values of 26, 24, 23, 15, 32, 36, 28, and 24. Compute the range, interquartile range, variance, and standard deviation. Round to 2 decimals, if necessary. Range Interquartile range Variance Standard deviation

Southern States Bank and Trust Southern States Bank and Trust monitors its drive-thru service times electronically to ensure that its speed of service is meeting the company's goal. A sample of drive-thru times at the UCF branch was recently taken and is shown here. The frequency is the number of service times and the time interval is the service time in minutes. Time Interval Frequency 10 - 19 5 20 29 12 30 39 13 40 49 11 50 59 6. Compute the mean for these sample data. (Round to the nearest 2 decimal places, if needed.)

The variance of the OLS estimator Select one: a. increases as the number of observations increases b. increases as the variance of the unobservable increases c. decreases as the number of observations increases d. decreases as the variance of the unobservable increases e. c) and d) are true   f. b) and c) are true g. a) and b) are true

Answer is wrong should be 4.25
