Find the range, vanance, and standard deviation for the given sample data. Include appropriate units in the results.Listed below are the measured radiation absorption rates (in Wikg) corresponding to various cell phone models. If one of each model ismeasured for radiation and the results are used to find the measures of variation, are the results typical of the population of cell phones that arein use?1.160.820.510.691.110.820.690.750.520.531.34

A developmental psychologist is interested in studying how long babies gaze at a photograph of a human face. To test this question, she shows a picture to a sample of six babies and records the length of their gaze in seconds. The data are as follows: 12, 17, 18, 20, 20, 29. Calculate the mean, median, mode, range, variance and standard deviation for the sample.

Consider the population with the values {2.1, 3.3, 7.6, 8.5), list all possible samples of size n = 2 WITH REPLACEMENT and find: d. population mean e. population variance f. population standard deviation. Please write your solutions in a legible manner and draw a box around your final answers.
Step 3 In order to use the defining formula for sample standard deviation, it is helpful to first calculate (x – x)² for each data value in the data set 1, 6, 7, 8, 9. Use the values in the data set and the previously determined mean, x = 6.2, to complete the following table. 7 8 6.2 6.2 6.2 6.2 6.2 х — х -5.2 0.8 2.8 (x – x)² 27.04 0.04 3.24 Submit Skip (you cannot come back)
