An independent knowledge, attitudes and practices survey on COFLU-20 was conducted in a large first-world country. The individual attitude scores were found to be normally distributed with the mean of 5 and a standard deviation of 1.3. For our current investigation of the 300 respondents, the mean score for attitude was found to be 5.6 with a standard deviation of 2.8 The researcher has asked you to use a 3% level of significance, to test whether the population mean score for attitude towards COFLU-20 is significantly different from 5. To conduct this test, you are required to: (d) Calculate the value of the test statistic for this test. (e) Calculate the p-value for this test. (f) Using the p-value approach, state the conclusion of this test. State your reasoning for arriving at your conclusion. (g) The researcher recommended that the level of significance be changed to 5%. How would this affect the conclusion arrived at in part (f)?
