Answer:
Type I error.
Step-by-step explanation:
Let's remember the definition of Type I error and Type II error:
A type I error is the rejection of a true null hypothesis, this means that we would get a "false positive" with this error.
A type II error is the non rejection of a not true null hypothesis, this error would give us a "false negative".
In this problem, we are told that the mean match score to identify a suspect is 80. However, the test shows that the mean match score is more than 80 when the person doesn't have a fingerprint match (and therefore the person would not be a suspect). Therefore, this person would appear as a suspect when he/she really isn't one. This means that the test is giving a "false positive". Thus, this is a type I error.
First one is 4/ 52 and the second second one is 4/51. (I did not reduce).
8/21,13/21 because .16/42=x/100 and then cross multiply and simplify

Answer:
£11,000.
Step-by-step explanation:
First, lets figure out how much 1g of gold costs by doing simple division:
£4000 / 200g = £20
1g = £20
Now we can multiply the cost of 1g of gold by 550g
£20 * 550g = £11,000
550g of gold would cost £11,000.
