A random sample of 863 births included 429 boys. Use a significance level of 0.05% to test the claim that 50.8% of newborn babies are boys. Do the results support the belief that 50.8% of newborn babies are boys?

? Question

Warm-Up

Sam walked to a nearby shop to purchase a gallon of ice cream. The shop is

400 meters from his house, and it took him 4 minutes to get there. At the

shop, it took 2 minutes to choose a flavor and purchase the ice cream. He

walked home in 3 minutes, at a faster pace than before so the ice cream

wouldn't melt.

Draw a graph that models Sam's distance from home (in meters) in terms

of time (in minutes). Label the graph with appropriate intervals and units.
