Answer:
4.02 meters.
Step-by-step explanation:
In the diagram, the length of the ladder is |AC|.
If the foot of the ladder is x meters from the base of the ladder
Then the distance of the ladder up the wall, AB=2x meters.
Using Pythagoras Theorem
Therefore, the distance of the ladder up the wall,
AB=2 X 2.01 =4.02 meters.
Critical values are basically cut-off values that indicate regions where the test statistic is unlikely to lie. The required critical value is 1.31.
<h3></h3><h3>What are critical Values?</h3>Critical values are basically cut-off values that indicate regions where the test statistic is unlikely to lie; for example, if the null hypothesis is true, the critical value is surpassed with probability alpha.
The value of α can be written as,
α = 1 - 0.81 = 0.19
Now, using the z-table the value of z will be,
z = 1.31
Hence, the required critical value is 1.31.
