A lecturer believes that less than 40% of all students understand hypothesis testing. To determine whether or not there is strong evidence to support his belief he tests a random sample of 50 students which shows the proportion of students who understand hypothesis testing to be 28%. The lecturer would

Since the calculated z value which is -1.73 lies between the two
critical values, reject null hypothesis at 5 % level of
significance but do not reject null hypothesis at 1% level of
significance. So the correct answer is B.

In a previous year, 63% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of 600 females aged 15 and older and finds that 387 are living alone. Is there sufficient evidence at the a = 0.05 level of significance to conclude the proportion has changed? Because npo (1-Po - U V 10, the sample size is V 5% of the population size, and the sample the...
