1. In the past years, the mean of Math test scores in a 4th grade class was 18. The following is a set of scores from 10 students from this year. A hypothesis testing needs to be conducted in order to compare the means to see if this year's students (based on this year's sample) are performing at the same level as the previous years. Data 3 - 5 > Subject # Score (Score)^2 1 22 484 2 12 144 3 15 225 4 20 400 5 26 676 6 29 841 7 25 625 8 20 400 1/2 9 24 576 10 19 361 Total 212 4732 What is the mean score of the sample? (Round up to the tenth place if it is necessary.) 2. Calculate the standard deviation of scores in the sample above in question number 1. (Round your answer to the tenth place.)
