Answer questions d, e, f and g   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)?

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)?
