ve scores on the national exam. An experiment is to be conducted to determine if there is sufficient evidence to make that claim. Which is a correct description of a Type I error? A Type I error would occur if evidence showed an improvement on the national exam and there really was improvement. A Type I error would occur if evidence showed an improvement on the national exam but there really was no improvement. A Type I error would occur if there was no evidence of an improvement on the national exam but there really was improvement. A Type I error would occur if there was no evidence of an improvement on the national exam and there really was no improvement.

Answer:

A Type I error would occur if there was no evidence of an improvement on the national exam but there really was improvement.

Step-by-step explanation:

A type 1 error simply occurs when we incorrectly reject a true null hypothesis. In the scenario above, An experiment was conducted in other it know if there is sufficient evidence to support a claim that a new teaching method developed improves students score. If this claim is actually true in the real sense. However, after conducting a statistical test, we conuded that there was no sufficient evidence to support her claim of improvement using the new method, hence, the claim was rejected. By rejecting the claim, a true null has been rejected. Hence, a type 1 error has been committed.

The bar diagram represents 24 hours in one day and shows a mark at 30%. If you sleep 30% of the day, how many hours do you sleep
Sedbober [7]
30% = 3/10

Number of hours you sleep = 24hours × 3/10
= 24hours ÷ 10 × 3
= 2.4hours × 3
= 7.2hours

Hope this helps! :)
