Between which two consecutive days is the greatest decrease in the number of likes? O Saturday and Sunday O Friday and Saturday O Thursday and Friday O Monday and TuesdayA student wants to earn a C for a class. To get this grade, the average of his six test scores must he 70. He has the following grades on ve tests: 60, 78, 65, 68, 72 What grade must the student get on the next test so that the average of his scores is 70? Enter your answer as a number, like this: 42 Compare the following two sample data sets: A: 5, 4, 6, 3,6, 7 B: 6, 5, 7, 6, 1, 8 Which data set has the greater sample standard deviation, and which data set has the greater range? Use the calculator if needed. Select the answer that is completely correct. GeoGebra Calculator 0 The sample standard deviation of set A is greater. The range of set A is greater. 0 The sample standard deviation of set A is greater. The range of set B is greater. 0 The sample standard deviation of set B is greater. The range of set B is greater. 0 The sample standard deviation of set B is greater. The range of set A is greater.
