Ablood test to detect prostate cancer in men gives a positive result 96% of the time if a person has prostate cancer, and it is 97% accurate for people who do not have the disease. what is the probability of getting a false positive result (that is, a person tests positive but does not actually have the ailment)?
a. 0.01
b. 0.03
c. 0.04
d. 0.07
e. 0.97

B. 0.03

Step-by-step explanation:

A blood test to detect prostate cancer in men gives a positive result 96% of the time if a person has prostate cancer.

This means the test detects 96% times correctly that the person has cancer. In the remaining i.e 4% times it detects incorrectly, which means the person has not cancer but he is detected that he has cancer. This is the case of false negative.

It is 97% accurate for people who do not have the disease.

This means the test detects 97% times correctly that the person doesn't have cancer. In the remaining i.e 3% times it detects incorrectly, which means the person has cancer but he is not detected that he has cancer. This is the case of false positive.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
