Is the proportion of Canadians whom have ever felt the urge to protest less than 40%? A random sample of n = 150 Canadians was taken, and each was asked the question: "Have you ever felt the urge to protest or join a protest?" There were two possible responses, "yes" or "no". These data can be found in column 2, starting in the 2nd row, of the .csv file. Download the data, then import it into R. To count the frequencies, use the function table(datafile_name$ column_name), for example, table(data$ x). You are to use these data to test if the proportion of all Canadians who have felt the urge to protest is less than 40%. (a) Select the appropriate statistical hypotheses below. A.

Question
Please help me with the following statistics question
For question (e), the options are:
Assuming that the null hypothesis is (false/true), the probability of (other populations of 150/other samples of 150/equal to/more data/greater than) will result in (stronger evidence against the null hypothesis than the current data/stronger evidence in support of the null hypothesis than the current data/rejecting the null hypothesis/failing to reject the null hypothesis) is __.
