Question Answered step-by-step According to an online source, 79.8% of students are right-handed… According to an online source, 79.8% of students are right-handed in Alberta secondary schools, 7.9% are left-handed, and 12.3% are ambidextrous (source: Census at School Canada, 2018-2019). A researcher wishes to test if these percentages seem reasonable among the general population of Albertans, so she obtains a random sample of 200 Albertans, from which she obtains the following frequency distribution:   Handedness Right-HandedLeft-HandedAmbidextrousFrequency1453520 Does the above give evidence to suggest the proportions of right-handed, left-handed, and/or ambidextrous Albertans differ from the proportions stated in the online source? Test at the 1% significance level. (8 marks) Math Statistics and Probability STATS 151 Share QuestionEmailCopy link Comments (0)
