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.
D. You can find a perpendicular line by finding the inverse equations (-(1/)2 x+3
Answer:
45= v
Step-by-step explanation:
9 = v/5
Multiply each side by 5
9*5 = v/5*5
45 =v
The slope of the line is -1
