1. Draw a histogram from all the data. Starting at the bottom row, for each set of 10 flips, place an “x” in the column corresponding to the number of heads that set produced. Your histogram should look similar to the example below:

2. Calculate the mean and standard deviation.
mean = _, standard deviation = _

3. Calculate the percent of the data that is within 1, 2, and 3 standard deviations of the mean.

within 1 standard deviation = _%
within 2 standard deviations = _%
within 3 standard deviations = _%
4. Compare your results to a normal distribution. Interpret any differences.

imma say 16%. sorry if its wrong. i'm doing the same stuff right now

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.

step-by-step explanation:

lol.

it's ok we all do this sometimes.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
