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. For our current investigation of the 300 respondents, the mean score for attitude was found to be 5.6 with a standard deviation of 2.8The 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)?
