Please I just hate to turn it in not being confident in my answers.

( 2nd guessing myself and if #2 is 3.5 ) or if my original formula is correct) Thanks in advance for any help <3

1) What is the range of the sample? The range would be the largest number minus the

smallest number in a group. The range is 8-0=8.

2) What is the interquartile range of the sample? (0,0,1,1,) 2,2, (3,3,5,8). The mean is

2+2/2=2. Q1 is (0+1/2) = 0.5 Q3 is (3+5/2) =4. Interquartile, Q3-Q1 is (4-0.5) =3.5.

3) What is the variance of the sample? (0+3+1+5+0+2+8+2+1+3)/8-1=2.125

(0-2.125) squared+(3-2.125) squared+(1-2.125) squared+(5-2.125) squared+(0+2.125)

squared+(2+2.125) squared+(8-2.125) squared+(2-2.125) squared+(1-2.125) squared+(3-

2.125) squared= 4.52, 0.76, 1.27, 8.27, 4.52, 0.02, 34.52, 0.02,1.27, 0.76=55.93 55.93/(8-

1) =7.99(variance)

4) What is the variant deviation of the sample? Squared roof of variance7.99=2.827

5) Based on your calculations, explain the distribution and variance of data. Based on my

calculations, the variables were distributed normally to gather information that was

collected.
