(giving brainliest) Calories consumed by members of a track team the day before a race are normally distributed, with a mean of 1,800 calories and a standard deviation of 100 calories. If a normal curve is sketched using these data, what is the range for 3 standard deviations to the right and to the left of the mean?

0–3,600
1,700–1,900
1,600–2,000
1,500–2,100

1,600-2,000

Step-by-step explanation:

just took this test and got it right. :)

I can confirm the answer is NOT C (1,600–2,000) because I took the test

I dont know what the actual answer is sorry.

Attached photo for proof its wrong

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
