For the sample data 7, 9, 10, 11, 13, 22find the standard deviation (give your answer in three decimal places). Answer:

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

use the dataset given below. 55,56,58,59,59,60,60,62,62,64,67,67,68,68,70,71 find the mean and standard deviation

Use the Student Unit Load data.  Student Unit Load 3, 12, 6, 9, 6, 12, 15, 12, 7, 9, 3   Find the mean, median, mode, range, standard deviation and variance. Use the range rule-of-thumb to find significantly high and low scores. Write the 5-number summary. Find the z-score for x = 15 Is x = 15 unusual in terms of a z-score?

d) Create a 99% Confidence interval for the mean. Provide a sketch of the critical value and calculate the standard error. Only for this part use o = 23.8
