Answer – C. the sample size 16 is too small

 

If we toss a coin 16 times in order to test the hypothesis H0: p = 0.5 that the coin is balanced, we can't use the z-test for a proportion in the situations because the sample size 16 is too small. The z-test is best used when the sample size is greater than 30; when the sample size is less than 30, t-test is more appropriate.

5x + 2y = 3<br> 2x+3y=-1<br> Solve
professor190 [17]

Answer:

x = 1

y = -1

Point = (1,-1)

Step-by-step explanation:

2x + 3y = -1   =   y = -2/3 - 1/3

5x + 2(-2/3 - 1/3) = 3

5x - 1 1/3 - 2/3 = 3

5x - 2 = 3

<u>     +2    +2</u>

5x = 5

<em><u>x = 1</u></em>

2(1) + 3y = -1

2 + 3y = -1

<u>-2           -2</u>

3y = -3

<em><u>y = -1</u></em>

sweet [91]
I think it’s c, because if the . next to the 12 means x then yes. There should be an c near 12 because we have no clue how much the notebooks are. If the . doesn’t mean x then it should be d.
