Only ONE of the following statements is true. Which one? Group of answer choices

We should only substitute s for σ in a one-sample procedure when n≤30.

We can never substitute s for σ in a one-sample procedure.

We can always substitute s for σ in a one-sample procedure.

We should only substitute s for σ in a one-sample procedure when n>30.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.

t hope this
