The world's smallest mammal is the bumblebee bat. the mean weight of 15 randomly selected bumblebee bats is 1.659 grams, with a standard deviation of 0.264 grams. find a 99.9% confidence interval for the mean weight of all bumblebee bats at the following confidence levels (two places after decimal): ( , ) find a 99% confidence interval for the mean weight of all bumblebee bats at the following confidence levels (two places after decimal): ( , ) find a 95% confidence interval for the mean weight of all bumblebee bats at the following confidence levels (two places after decimal): ( , ) find an 80% confidence interval for the mean weight of all bumblebee bats at the following confidence levels (two places after decimal): ( , )

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.
