Answer:
You can reject the null at the 10% and 5% level of significance, but cannot reject the null at the 2%, or 1% level of significance. ( D )
Step-by-step explanation:
let : P = 0.6
x = 135 , n = 200
<em>p </em>= 135 / 200 = 0.675
H0 : P = 0.6
Ha : P ≠ 0.6
performing the test statistic = ( 0.675 - 0.6 ) / 
= 0.075 / 0.0346 ≈ 2.17
p-value = 2 * P ( Z > - 2.17 ) ( using excel function ; NORMSDIST )
= 2 * 0.015 = 0.03
Answer: (c)
Step-by-step explanation:
Given
Function
is 
Also,
is the transformation of 
From the graph, it is clear that
passes through the point 
Now check the option which satisfies the condition
option (c) seems to obey it

Therefore, option (c) is correct.
1/2 / 4
The formula = keep, change, flip
Keep 1/2
Change the sign: / to ×
Flip 4 to 1/4
That equals 1/2 × 1/4 = 1/16
Answer = 1/16
