An independent knowledge, attitudes and practices survey on COFLU-20 was conducted in alarge first-world country. The individual attitude scores were found to be normally distributedwith the mean of 5 and a standard deviation of 1.3. For our current investigation of the 300respondents, 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 populationmean score for attitude towards COFLU-20 is significantly different from 5. To conduct thistest, you are required to:(2) Explain the meaning of 3% level of significance' to the researcher.(b) State whether this is a one-tailed test or a two-tailed test. Give season for your answer.(c) State the null and the alternative hypotheses for this test.(d) Calculate the value of the test statistic for this test. (e) Calculate the p-value for this test.O Using the p-value approach, state the conclusion of this test. State your reasoning for arrivingat your conclusion.(2) The researcher recommended that the level of significance be changed to 5%. How wouldthis affect the conclusion arrived at in part (f)?

(a) The “3% level of significance” indicates that there are 0.03 chances of rejecting the null…
