DIRECTIONS:Enter the hypothesis test amount.(1 point)Enter alpha value.(1 point)Enter how many were actually brown.(1 point)Enter the sample size.(1 point)Access this helpful video:State the results and interpret the results here:( 6 points)Sample size = 100, 8% are brown M&M's. Alpha=.05 to test the claim that the % of brown M&M's is 13%.Video

DIRECTIONS:Enter the hypothesis test amount.(1 point)Enter alpha value.(1 point)Enter how many developed cancer.(1 point)Enter the sample size.(1 point)Access this helpful video:State the results and interpret the results here:( 6 points)Cell phones and cancer. Out of 420,095 subjects, 135 developed cancer. Using a .005 significance level,test the claim that cell phone users develop cancer different from .0340% for people who do not own cell phones.Video
