Answer:
C) The test provides the convincing evidence that the proportion is greater than 90%, but the actual proportion is equal to 90%.
Step-by-step explanation:
Options are missing from the question. The complete question with its options is shown in the image below.
We need to describe about the Type 1 error. In Statistics there are two main errors: Type 1 error and Type 2 error.
- Type 1 Error occurs when we reject the null hypothesis when infact its true.
- Type 2 Error occurs when we fail to reject the null hypothesis when infact its false.
In the given case the Null Hypothesis is:
The proportion of all washers produced with the specified diameter is equal to 90 percent.
The Type 1 error will occur when the test results will reject the Null hypothesis and accept that the specified diameter is greater than 90% , when infact the Null hypothesis is true and actual proportion is equal to 90%.
Therefore, the correct option will be:
C) The test provides the convincing evidence that the proportion is greater than 90%, but the actual proportion is equal to 90%.
Q= 9 D=3 N=5 those are the answers
Answer:
0.35, 0.359, 1
Step-by-step explanation:
0.35 would be 0.350 meaning its less than 0.359
The length of side of triangle is 5 units and length of side of pentagon is 1.5 units.
<u>SOLUTION:</u>
Given, An equilateral triangle has sides of length units.
Then, perimeter of the triangle will be
A regular pentagon (5 sides) has sides of units.
Then, perimeter of the pentagon will be
We have to find the dimensions of each shape
. Now, the perimeter of the triangle is twice the perimeter of the pentagon,
So,
Then, length of side of triangle
Length of side of pentagon
We have to neglect, negative sign as lengths can’t be negative. Even if we change the sign above all conditions are satisfied.
