Answer:
It is not a Type I error neither a Type II error.
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.
85(2)= 170
15(4)(3)= 180
3.2(45)(8)= 1152
I don't know if this is right or if you're teacher will allow this, but
you could put that as 7(x+8) because if you were to turn it into a solved thing, it would become 7x+56.
I don't know if this is right though.
