The probability of flu symptoms for a person not receiving any treatment is 0.045. In a clinical trial of a common drug used to lower cholesterol, 53 of 1073 people treated experienced flu symptoms. Assuming the drug has no effect on the
likelihood of flu symptoms, estimate the probability that at least 53 people experience flu symptoms. What do these
results suggest about flu symptoms as an adverse reaction to the drug?

(a) P(X 253) =
(Round to four decimal places as needed.)

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.

look at the picture i have filled out a table for it. hope this .
