d. A social worker is interested in examining the intelligence of all the children in one foster home. Each child was given a standardized intelligence test and their score are as follows: 100, 110, 98, 92,871. Compute the sum if squares 2. Compute the variance 3. Compute the standard deviation 4. Explain what the SD means in plain English

Find the​ range, variance, and standard deviation for the given sample​ data, if possible. If the measures of variation can be obtained for these​ values, do the results make​ sense? Biologists conducted experiments to determine whether a deficiency of carbon dioxide in the soil affects the phenotypes of peas. Listed below are the phenotype​ codes, where 1 equals ​smooth-yellow, 2 equals ​smooth-green, 3 equals wrinkled ​yellow, and 4 equals ​wrinkled-green.   a. The range of the sample data is ​(Type an integer or a decimal. Do not​ round.)   b. the standard deviation of the sample data is ​(Round to one decimal place as​ needed.)   c. The variance of the sample data is ​(Round to one decimal place as​ needed.)

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.
