Last semester you took 3 final exams and you want to figure out which exam score really is your best score. here are the scores from your classes. which of your three exam scores is the worst when compared to the other students in your classes? math: your score = 78, class mean = 82, standard deviation = 5 history: your score = 85, class mean = 87, standard deviation = 4 english: your score = 80, class mean = 76, standard deviation = 2.5.

Analyze the data sets below. data set a 25,25,25,26,26,26,27,28,28,29,30,31 ,31,32,33,33,34,35,35,35 data set b 25,25,25,26,26,26,26,27,27,27,27,28 ,28,29,29,30,31,31,32,34 which of the following statement are true? select all that apply. a. data set a is relatively symmetric and data set b is skewed left. b. the means of the data sets are within 3 units from eachother. c. the data sets have the same standard deviation. d. the mean of data set a is 27.95 and the mean of data set b is 30. e. the data set b has a higher standard deviation than data set a. f. the mean and median of data set a are close in value.

Will make ! for correct answer the dot plot below shows the number of toys 21 shops sold in an hour. is the median or the mean a better center for this data and why? a. median; because the data is not symmetric and there are outliersb. median; because the data is symmetric and there are no outliersc. mean; because the data is symmetric and there are no outliersd. mean; because the data is skewed and there are outliers
