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.
Answer:
y<1
Step-by-step explanation:
12y/12
12/12
The LCD is 24
2 * 8 16
3 * 8 24

8 * 3 24
Because 16 over 24 is greater than 15 over 24
2/3 is greater than 5/8
