5. At the same time on the other side of Earth, the gravitational attraction between the Moon and water on Earth nearest the Moon causes another bulge of water to lift upward away from Earth's surface. Sketch in this second bulge on the figure above.

\( \int _ { 0 } ^ { 3 } \int _ { 0 } ^ { 2 } [ \sin ( x \cdot y ) d x ] d y \)

Each year, a group surveys 50,000 households to study internet usage. In one area of the study, the group is interested in finding out how many hours a day the household spends streaming video from the internet. Describe the five basic steps in a statistical study with an example of their application below. D. Discover if there is interest in this study. In this case, we ask other researchers if they would be interested in reviewing the collected data. Describe the fourth step in this statistical study. Choose the correct answer below. A. Act on the collected data. In this case, we see that some households spend 0 hours streaming internet video and so we show these households how to stream video online. B. Use the sample statistics to infer the population parameters. In this case, based on the data gathered, the group estimates the average time per day that a household spends streaming internet video. C. Estimate any missing data. In this case, we would estimate the data for any households that we could not collect data from. D. Use the sample statistics to infer the population parameters. In this case, the group estimates how many households have internet access.

a. \( 2 \frac{1}{3} \div \frac{5}{6} \)

The mean points obtained in an aptitude examination is 183 points with a standard deviation of 13 points. What is the probability that the mean of the sample would differ from the population mean by less than 1.1 points if 73 exams are sampled? Round your answer to four decimal places.
