1. Z = 1.75

2. False Positive

Step-by-step explanation:

1. mean = 1750 calories

standard deviation, sd = 200 calories

value of interest, x = 2,100

z-score is computed as follows:

Z = (x - mean) / sd

Z = (2100 - 1750) / 200

Z = 1.75

2. A false positive happens, when a negative case is detected as a positive case
