andrew11 [14]

Answer:

The null and alternative hypotheses are:

H_{0}: \mu = 170

H_{a}: \mu >170

Under the null hypothesis, the test statistic is:

z=\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}} }

         =\frac{180-170}{\frac{35}{\sqrt{225}} }

         =\frac{10}{2.33}

         =4.29

Now, we have to find the right tailed z critical value at 0.10 significance level. Using the standard normal table, we have:

z_{critical} = 1.28

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.
