Help with 1 and maybe the rest if I did them wrong...Would I use t test or z test

TechCrunch.com reported in 2014 that the completion rat (MOOCs found that 75 completed the course. Test, using a 5% level of significance, the claim that the population proportion of students completing MOOCs has increased 1. e for massively open online courses ) is only 6.5%. Suppose a new study of 1000 randomly chosen students taking a MOOC a. (2 points) State the null and alternative hypotheses (2 points) What calculator test will you use? List the requirements that must be met to use this test, and indicate whether the conditions are met in this problem. b. 2 test-known c. (2 points) Run the calculator test and obtain the P-value. 0,0498 d. (2 points) Based on your P-value, will you reject or fail to reject the null hypothesis? Farl to reject. Pvalue is greater than o.05 (2 points) Interpret your conclusion from part d in the context of this problem. The popolation proportion of sfodents completing MOOCs e. nas not increased

Explanation / Answer

Solution:-
a. H0: p = 0.065 H1: p is not equal to 0.065

b. p = 75/1000 = 0.075 , q = 1-p = 1-0.075 = 0.925
  
Z = (0.075-0.065)/sqrt((0.075*0.925)/1000) = 1.2006
