Answer:

96 laps

Step-by-step explanation:

2 hours = 2 * 60 = 120 minutes

So now the question would be as given below:

8 laps in 10 minutes so how many laps in 120 minutes.

Since, no. of laps and minutes are in proportion.

$\therefore \: \frac{8}{10} = \frac{x}{120} \\ \\ x = \frac{8 \times 120}{10} \\ \\ x = \frac{960}{10} \\ \\ x = 96 \:$

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.
