Which of the following statement is true? min Q1 median Q3 max mean sd n missing
30 57 69.5 77 99 65.075 16.09 361 200

a. The minimum value of 30 would be identified as out outlier in a box plot.
b. The standard deviation estimate is not possible because score is a whole number.
c. There were more survey respondents who reported job satisfaction scores less than 57 than survey respondents reported job satisfaction scores greater than 77.
d. These statistics are not meaningful because score is not a numerical variable.
e. There is evidence that the distribution of score is right-skewed.

Ok here we go ..there are plenty of ways to solve such math problems but we will go for the smartest and easiest ..5x+2y=7  -2x+6y=9we rearrange them into the following ..by multiplying the 1st equation by 2 it becomes 10x + 4y = 14we rearrange it and so it becomes 10x = 14 - 4yas for the second equation we multiply it by 5 and rearrange it so it becomes as to the following ..-10x + 30y = 45rearranging so 10x = 30y -45now 10x equals both 14 - 4y and 30y -45so   14 - 4y = 30y -4531 = 26yy= 31/26 = 1.19 or around 1.2so by now we can calculate x easily as  -2x+6y=9so 2x = 6y -9 = 6 * 31/26 - 9 = -1.84  then x = - 0.92 or around -0.9best luck!
