In a study focusing on student's achievement. 100 students were classified as low, average, or high achieving, based on their responses to a series of questions. These are the data that were collected from the classification representing their attitudes about achievement. Based on data from previous years, the researchers were expecting that 15% of students would be low achieving, 60% would be average achieving, and 25% would be high achieving. Use this information to create a hypothesis. Low achieving 12 Average achieving 54 High achieving 34 a) What would the df for this test? b) What's the critical value? c) What's the value of the test statistic? d) Should the researchers reject or retain the null hypothesis? (Enter 'Reject' or 'Retain')
