Suppose you have 3 quizzes and want an average of 7 points. List at least five ways this average can be accomplished. keep in mi
Sunny_sXe [5.5K]

Answer:

4,9,8 = 4+9+8 = 21

9,9,3 = 9+9+3 = 21

6,7,8 = 6+7+8 = 21

8,8,5 = 8+8+5 = 21

5,7,9 = 5+7+9 = 21

Step-by-step explanation:

The question says you get 7 points per quiz out of 3 quizzes.

7+7+7 = 21

Now that we know that we need a total score of 21, we therefore need to distribute it among the three quizzes.

Remember;

None of these scores are to be higher than 10. We need to add up scores below 10.

4,9,8 = 4+9+8 = 21

9,9,3 = 9+9+3 = 21

6,7,8 = 6+7+8 = 21

8,8,5 = 8+8+5 = 21

5,7,9 = 5+7+9 = 21

All of these gives 7 as average.

Tom [10]
Z-test should be used when the parent standard deviation is known and the sample size is greater than or equal to 30 (to satisfy the Central Limit Theorem). A T-test should be used when these two rules do not apply.
