Answer:
D: Reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually 10%.
Step-by-step explanation:
In statistics, type I error is when we reject the null hypothesis even when it is true.
Now, the claim which is the null hypothesis is that that 10 % of children suffer from a certain disorder.
This means that a type I error will be;
Reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually 10%.
Answer:
The correct option is A. 198 degrees
Step-by-step explanation:
Consider the provided information.
87 percent of students worked at least sometime during their undergraduate career and 13 percent did not work at all.
Another question showed that 32 percent of the students worked throughout their undergraduate career.
87 percent of the students worked at least sometime during the college. Out of them 32% worked throughout the college.
Therefore, the students who worked sometime during their undergraduate career, but not throughout are:
(87-32)% = 55% .
As we know the angle measure in circle is 360 degrees.
55% of 360° is:
![\frac{55}{100}\times360= 198](https://tex.z-dn.net/?f=%5Cfrac%7B55%7D%7B100%7D%5Ctimes360%3D%20198)
Hence, the measure of central angle would be 198 degrees
Therefore, the correct option is A. 198 degrees
