Step-by-step explanation:
Let be the true mean match score. The null hypothesis is and the alternative hypothesis is (upper-tail alternative). When the test shows that the mean match score is more than 80 when actually is equal to 80 a Type I error is made. On the other hand, when the test shows that the mean match score is equal to 80 when actually is more than 80 a type II error is made. Therefore, when the test shows that the mean match score is more than 80 when the person does not actually have a fingerprint match, does not correspond to a Type I error neither to a Type II error.

Answer: $140
Step-by-step explanation:
1/4 × 560 to buy a coat
