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:
a. 13 years
b. 27950 students
Step-by-step explanation:
Let x be the number of years since the initial year 2005. In 2005, , in 2006, , and so on.
For college "A" the number of students is given by the function:
For college "B" the number of students is given by the function:
Matching these expressions you have the value of x for which the two colleges have the same number of students.
Then, the two colleges will have the same number of students 13 years later, that is, in 2018.
The number of students that each colleges will have in 2018 will be students.
