Answer: 69
Step-by-step explanation:
Let the original employee be x , this means that
116% of x = 80
= 80
116x = 8000
divide through by 116
x = 8000/116
x = 68.96551724
Since we are dealing with employees , therefore x ≈ 69
This means that there were 69 employees originally
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%.
Answer:
-16
Step-by-step explanation:
So you want to change the - into a + and the negative sign before the 13 also into a plus. So it is -29 + 13 and that would be -16 ^.^ Hope this helped!!
K is less than 12, so if you put k first, it would be written as k < 12.
However, you are needing to use >.
Therefore the answer is
12 > k (This says that 12 is greater than k, but it can also be said as k is less than 12, if read backwards)
