Mr. taylor's 4th grade class uses skittles to learn about probability. they open several randomly selected bags of skittles and sort and count the different colors and want to determine if skittles are evenly distributed by color.
col1 color red orange yellow purple green
col2 count 107 101 87 115 10

a) choose the appropriate null and alternate hypotheses. b)what is the p-value? c)what is your conclusion?

The skitties are not evenly distributed by colour

Step-by-step explanation:

Given that Mr. T  aylor's 4th grade class uses Skittles to learn about probability. They open several randomly selected bags of Skittles and sort and count the different colors and want to determine if Skittles are evenly distributed by color.

(Two tailed chi square test)

If all are equally distributed then expected values would be equal to 420/5 =104

Observed                       Red   Orange  Yellow   Purple   Green  Total

                                       107          101      87           115           10     420

Expected                         104          104     104          104         104    420

Chi square0.08650.08652.77881.1634584.961589.0769

Chi square is calculated as (obs-exp)^2/exp

Total chi square = 89.0769

df = 4

p value = <0.00001

Reject null hypothesis

The skitties are not evenly distributed by colour

if you use photomath right away it will give you the answer not like this app that you have to wait for people.
