1. To get through a page in a statistics book can take

three or four times longer than to get through a page

in a nonnumerical book. True

Basic math problems:

2. -12 + 8 = －4

3. 4 * (-5) = －20

4. -5 / -4 = 1.25

5. 3 * 7 - 6 = 15

6. 4^3 = 64

7. ((8 + 3) * 2) - 5 = 17

8. ((2)^2)^3 = 64

9. 17/13 * 13/17 = (rounded to the nearest unit) 1

10. If 3y + 5 = 8 then y = 1

11' For an agricultural experiment, 300 seeds were planted in one plot and 200 were planted in a second plot. If exactly 25 percent of the seeds in the first plot germinated and exactly 35% of the seeds in the second plot germinated, what percent of the total number of seeds germinated? (300*0.25+200*0.35)/500 = 29%

Which of the following(s) can be considered (a)

variable(s):

12' The IQ. Yes

13' The price of a stock. Yes

14' The number of hours in a day. No

15' The GPA. Yes

16' The gravity constant g = 9.81 m.s^-2. No

17' The summation sign is usually represented by

A) The Latin uppercase phi B) The Greek lowercase omega

C) The Latin lowercase t D) The Greek uppercase sigma.

Compute the mean (M), median (Md) and mode (Mo) for

this distribution: 3,3,3,6,6,8,8,9,11,12

18' M = 6.9

19' Md = 7

20' Mo = 3

Find the range (R), variance (V) and standard

deviation (s) for the following set of values: ...
