Week-7 Decision making

For this week is very useful and interesting because we are all living with this.

According the video, The woman was sitting, on her table have a phone and speaker.
So if her speaker are playing the music like this (あいうえお〜〜〜)
and her phone's ring tone is like this （ＡＩＵＥＯ〜〜）

It could be ending in 4 possibilities

1. HIT : positive response when there is a signal = the phone is ringing and she picks up the phone (ringtone = signal, speaker music = noise).

2. MISS : negative response when there is a signal = the phone is ringing and she doesn't pick up. (she miss the signal (ringtone))

3. False alarm : positive response when there is no signal = the phone doesn't ring but she check/pick the phone up.

4. Correct rejection : negative response when there is no signal = the phone doesn't ring and she doesn't pick up the phone.

D' (D prime)

In this case = speaker are playing（あいうえお〜〜）the same sound of ringtone（あいうえお〜〜）.
