<h3>The ladder will reach a height of 11.8 feet up the wall</h3>
<em><u>Solution:</u></em>
The ladder, wall and base of the ladder from wall forms a right angled triangle
Length of ladder forms the hypotenuse
Length of ladder = 12 foot
base of the ladder from wall = 2 feet
<em><u>To find: height of wall</u></em>
By pythagoras theorem.

Where,
"c" is the Length of ladder
"a" is the base of the ladder from wall
"b" is the height of wall
Substituting the values,

Thus, the ladder will reach a height of 11.8 feet on wall
<em>=</em><em>5</em><em>^</em><em>6</em><em>/</em><em>5</em><em>^</em><em>4</em>
<em>=</em><em>5</em><em>^</em><em>(</em><em>6</em><em>-</em><em>4</em><em>)</em>
<em>=</em><em>5</em><em>^</em><em>2</em><em> </em><em>ANSWER</em><em>.</em><em>.</em>

Step-by-step explanation:
Answer:
Yes, the test was conducted with a risk of a type I error.
Step-by-step explanation:
If we reject the null hypothesis, does this mean that we have proved it to be false beyond all doubt? Explain your answer.
Yes, for a null hypothesis to be rejected, it has being proven beyond all doubt that the null hypothesis will not work. the normal distribution has being used for the probability calculation.
if the null hypothesis is rejected and the alternative hypothesis is accepted, a type I error as occur.
In general terms:
‘a hypothesis has been rejected when it should have been accepted’. When this occurs, it is called a type I error.
