Big Al's Steak House and Trail's End both claim to have the shortest wait times in
town. To check out the claims, Ramon, a restaurant reviewer, records the time it
takes to be seated without reservations. The results of wait times for 8 visits to each
restaurant are shown in the table.

Big AI's Steak House Wait Times (minutes): 5,13,22,7,20,21,20,12

Trail's End Wait Times (minutes): 11,19,14,14,15,20,10,17

a. Describe the populations and samples for this problem.
b. Calculate the mean wait time for each of the two restaurants.

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.
