Answer:
The null and alternative hypotheses are:
Under the null hypothesis, the test statistic is:
Now, we have to find the right tailed z critical value at 0.10 significance level. Using the standard normal table, we have:
Since the test statistic is greater than the z critical value, we therefore, reject the null hypothesis and conclude that there is sufficient evidence to support the claim that the university students weigh more than the population.
